Angle of Attack

www.design-engineering.com

B

y 2009, when Boeing delivered its 6,000th 737 nearly 42 years after the first one saw commercial service in 1967, the medium-sized narrow-body airliner had become the single most successful aircraft in aviation history. At the height of its popularity, it’s estimated that two 737s were taking off or landing, somewhere in the world, every five seconds.

It’s not surprising then that, when Airbus announced it was developing the A380neo, a revamped version of the 737’s arch-rival, Boeing decided to forgo a brand new airframe in favor of the 737 MAX, a re-engine of its superstar aircraft.

After all, the A380neo set sales records in its first year, even breaking into historically Boeing-exclusive customers like American Airlines.

With the wolves at its gates, Boeing promised the 737 MAX would have longer range, better fuel efficiency and even a few more seats than its predecessor and competitor. To boot, it would still be essentially the same 737 many pilots were already cleared to fly and therefore wouldn’t require lengthy and expensive re-certification.

Delivering on those promises, though, entailed unconventional or, given the deadly crashes that led to the 737 MAX 8’s grounding in March, dubious mechanical and software engineering, critics say. Simply put, to get the plane to fly farther using less fuel required a much larger engine. Making sure those big engines weren’t too close to the ground, in turn, required placing them significantly forward of the wings’ leading edge and higher up.

As a result, the engine’s placement makes the plane prone to pitching up when power is applied, as in take off. What’s worse, the more it pitches up, the more the plane’s aerodynamics push it toward an angle of attack (i.e. wing angle relative to oncoming airflow) that would induce stall conditions.

To counteract this tendency, Boeing implemented the Maneuvering Characteristics Augmentation System (MCAS), a component of the plane’s flight computer software designed to take control and pitch the nose down if angle of attack became too severe. What exactly caused Lion Air Flight 610 last October and Ethiopian Airlines Flight 302 in March to crash is still unclear, but investigators have singled out MCAS as a likely factor in both incidents.

While all modern aircraft have autopilot and flight assistance systems on board, MCAS seems to have some disturbing differences. First, it wasn’t until after the Lion Air crash that pilots were briefed that MCAS even existed let alone how to turn it off should it malfunction. In addition, the autonomous system relied on a single point of failure, a small and somewhat delicate wing-like angle of attack sensor outside the pilot’s window. Finally, MCAS was designed to wrest control away from and even fight the pilots desperately trying to keep the plane from crashing.

Whatever the final investigation reveals, MCAS will hopefully stand as a stark reminder to the industry and developers in general, that so-called “smart” systems, or software AI, isn’t the new duct tape, engineering fairy dust that magically spackles over fundamentally flawed hardware design. At the end of the day, software and hardware engineering are polar opposite disciplines. The infinite malleability of software code makes it all too easy to simply push out a patch; hardware development, on the other hand, carries a painfully high cost of not getting it right the first time.

UofW-developed wheel units to slash EV development costs

R

esearchers at the University of Waterloo announced they have developed a modular wheel unit that’s affordable to produce and removes much of the complication associated with electric vehicle design.

The self-contained unit combines a wheel and an electric motor, along with braking, suspension, steering and control assemblies to form a modular unit that can be bolted to any vehicle frame.

“The idea is modularity and plug-and-play control capability,” said Amir Khajepour, a mechanical and mechatronics engineering professor at Waterloo. “Our wheel unit, in a sense, is a full vehicle with only one wheel. All that’s missing is a body.”

According to Khajepour, a mass-produced wheel unit, or corner module, would significantly reduce production costs while also opening up space for passengers that would otherwise be devoted to mechanical components. At present, the prototyped units weigh about 40 kilograms, have about 25 horsepower and feature active wheel cambering.

The next step, Khajepour said, is to scale wheel unit for

large utility and commercial vehicles. That would pave the way for more cost-effective production of low-volume, specialized vehicles with customized bodies in fields including mining, forestry and rescue operations.

“It’s an economy of scale problem,” said Khajepour, who serves as director of the university’s Mechatronic Vehicle Systems Lab. “Corner modules would allow us, without enormous development costs, to make vehicles that are specific for each application, for each function, by concentrating only on the design of the body and the user interface.” https://uwaterloo.ca/waterloo-engineering-research

Army researchers foresee AM as transformative for battlefield logistics

U

.S. Army researchers are looking into metal additive manufacturing to create steel alloy as a way to transform combat logistics. At the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, materials manufacturing scientists say this technology may change everything, although readily printed reliable 3D parts are still in the future.

“You can really reduce your logistics footprint,” said Dr. Brandon McWilliams, a team lead in the lab’s manufacturing science and technology branch. “Instead of worrying about

carrying a whole truckload, or convoys loads of spares, as long as you have raw materials and a printer, you can potentially make anything you need.”

Using powder bed fusion, the Army researchers are building parts from an alloy, called AF96, in powder form. The Air Force initially developed AF96 as an economical yet high-strength and hardness alloy for bunker-busting bomb applications. The resulting steel alloy parts are approximately 50 percent stronger than those commercially available, McWilliams said, but they have yet to be battlefield tested.

“We’ve printed some empeller fans for the M1 Abrams [Main Battle Tank] turbine engine and we can deliver that part—they can use it, and it works,” McWilliams said. “But it’s not a qualified part. In terms of a battlefield scenario, that may be good enough to be able to get your tank running again for hours or days if that’s important to the mission, but on the other hand, we still need to be able to answer, does this perform as good as the OEM part? Does this perform better?”

Currently, McWilliams said the laboratory is working with industry and academic researchers to model new alloy designs and perform computational thermodynamics. www.arl.army.mil

Engineering researchers look to make supersonic commercial flight viable

F

lying from Los Angeles to New York City in an hour sounds great but a sky full of supersonic-capable planes breaking the sound barrier (767 mph) along with the characteristic sonic boom would ruffle more than a few feathers.

To lessen this problem and make super or even hypersonic commercial flight viable, University at Buffalo aerospace engineer, James Chen, is working to solve problems associated with exceeding the sound barrier by investigating how air acts at super and hypersonic speeds.

“Reduction of the notorious sonic boom is a just a start,” says Chen, PhD, assistant professor in the Department of Mechanical and Aerospace Engineering at UB’s School of Engineering and Applied Sciences. “In supersonic flight, we must now answer the last unresolved problem in classical physics: turbulence.”

“There is so much we don’t know about the airflow when you reach hypersonic speeds,” he adds. “For example, eddies form around the aircraft creating turbulence that affect how aircraft maneuver through the atmosphere.”

To unlock this mystery, Chen’s research extends Ludwig Boltzmann’s classical kinetic theory into high-speed aerodynamics, including hypersonic speed, which begins at Mach 5 or 3,836 mph.

Traditionally, engineers have used wind tunnels or direct numerical simulations (DNS) to solve such aerodynamic problems. However, those methods, he says, breakdown when it comes to studying turbulence patterns at super and hypersonic speeds.

Instead, Chen work focuses on morphing continuum theory (MCT), which provides computationally friendly equations and a theory to address problems with hypersonic turbulence.

“The Center for Computational Research at UB provides a perfect platform for my team and me at the Multiscale Computational Physics Lab to pursue these difficult highspeed aerodynamics problems with high-performance computing,” says Chen.

Ultimately, Chen says his work could lead to better supersonic and hypersonic aircraft design, including everything from the vehicle’s shape to what materials it is made of. The goal, he says, is a new class of aircraft that are faster, quieter, safer and less expensive to operate. http://engineering.buffalo.edu

Canada Supercluster announces first cohort of projects

C

anada’s Digital Technology Supercluster announced its first seven projects, totalling $40 million in investment over three years, comprised of $15 million from the supercluster and more than $25 million from industry, research and academic partners.

The first cohort is focused on advancing Canada’s development and application of digital technologies to solve some of the most pressing challenges in the natural resources, healthcare, and industrial sectors. These projects can strengthen the early detection and treatment of skin cancers, improve the prediction of manufacturing failures and analyze the economic and enviromental impacts of resource projects.

Each project is industry-led, with each project team including five to nine partners collaborating to tackle ambitious technology development challenges that require their collective expertise to solve. The partners leverage British Columbia’s and Canada’s powers in data analytics, genomics, quantum computing, as well as virtual, mixed and augmented reality.

The seven projects approved under the Technology Leadership Programs include the Learning Factory Digital Twin; Predictive Analytics for Manufacturing Processes; Forest

Machinery Connectivity; Earth Data Store; Tailored Health – Pharmacogenetics; Dermatology Point-of-Care Intelligent Network; and Secure Health & Genomics Data Platform.

“Canadian businesses face new challenges, but also new opportunities presented by the Fourth Industrial Revolution,” said Charles Lavigne, CEO and Co-founder of LlamaZOO Interactive. “By integrating technologies including AI, simulation, IIoT, big data fusion and visualization, we can invent new ways of digitally twinning the manufacturing process.

These digital twins will then be used to derive new meaningful insights, enhance the learning process and accelerate not only business outcomes but also educational outcomes for Canadian industries.” www.digitalsupercluster.ca

Solidworks CEO Gian Paolo Bassi during his keynote speech at Solidworks 2019.

NOW WITH LESS SOLIDWORKS Dassault Systemes rebrands popular CAD user conference to reflect wider marketing push.

By Ralph Grabowski

A

year ago, Dassault Systemes promised Solidworks users that it endorsed two pillars: Solidworks and 3dExperience. That announcement was important, because two million Solidworks users had been rejecting Dassault’s pleas to switch to its 3dExperience line of software. Users saw no benefit in paying a lot more annually for cloud-based CAD programs with a different user interface running on a proprietary database incompatible with existing Solidworks models and that weren’t necessarily shipping yet. So, the two pillars announcement was Dassault’s acknowledgment that the desktop Solidworks software was important to users.

Much to Dassault’s chagrin, they had acquired not only the most successful mid-range 3D modeler, but also one that keeps getting more successful. In 2018, March/April | 2019

DES_MARCHAPRIL2019_LAZ.indd 14

for the first time, more than 80,000 licenses of Solidworks were sold – about double the next closest competitor.

Dassault is the biggest of the CAD vendors. This year, it’s expecting to earn revenues of US$4.6 billion. It has a single R&D department spending US$650 million a year and employing 41 percent of the workforce. With its CGM solid and surface modeler, Dassault has arguably the most powerful CAD code out there, offering 12 “brands” (its name for software) in 11 target markets, including one as traditionally non-CAD as fashion.

From Solidworks World to 3dExperience.World Dassault offered Solidworks users a compromise. In exchange for them getting to keep their permanent-licensed desktop software, they should branch out to adja-

cent CGM-based software. But here Dassault was unhelpful to the cause: It would announce CGM software designed for Solidworks users, and then either cancel the project or else delay the launch, sometimes by years.

The fantasy of two million customers paying expensive 3dExperience subscriptions annually for a single code base (called “V6”) is, however, too delicious for Dassault to abandon. And so last year the keynote speeches by executives at Solidworks World 2018 were all about 3dExperience. This year, at Solidworks World 2019, the keynotes were all about 3dExperience. And the keynotes at next year’s... well, there won’t be a Solidworks World next year.

Dassault has renamed it 3dExperience.

World. The traditional black backpacks handed out this year were already emblawww.design-engineering.com

2019-04-10 1:56 PM

CADReport 15 zoned with 3dExperience.World. CAD editor Roopinder Tara interviewed a Dassault vice president who anticipates 30,000 attendees at next year’s event, up from this year’s 6,000.

The change in name tells us that Dassault is fed-up. Corporate executives had patiently painted pictures of the bright new futures in which all aspects of CAD are unified into a single whole, where everything happens in an instant, looking dreamy and swooshy. Approving designs wirelessly while riding in a taxi speeding through the canyons of New York City. What’s not to like?

This year, however, the tone changed from the brightly-patient to something more like exasperatedly plaintive. Keynote speaker after speaker explained to the wary audience that Dassault has spent many years developing its wondrous software; the many thousands of employees who have worked so hard on the many software programs ready to be deployed.

“We always promised you to broaden and deepen our portfolio solutions; we always told you we would integrate everything that we do, whether it is desktop

DES_MARCHAPRIL2019_LAZ.indd 15

or the cloud,” Solidworks CEO Gian Paolo Bassi pleaded to the crowd. “We also promised to give you choice, to help you at your own pace, to give you flexibility.

I hope you recognize that we made good on all those commitments.”

When Mr. Bassi and Dassault Systemes CEO Bernard Charles paused their speeches to wait for applause, at times there was none. At one point, one of them muttered “Thank you, thank you” to the muted ballroom. Mr Bassi admitted, “You are a tough crowd.”

Then he tried flattering his audience: “You have very, very high-end requirements. Your designs are becoming ever more sophisticated. You want the confidence of multi-physics simulation. You expect zero defects at the design stage.

I think Solidworks users might be more interested in better ways to construct complex fillets than getting around to igniting the next Industrial Renais-

sance. As attendee Dwight Livingston wrote afterwards on the Solidworks Forum, “Gian Paolo Bassi loves my passion. I am pretty sure he says that every convention. But my passion is Solidworks, not 3dExperience.”

Confusion Over 3dexperience.

Works 3dExperience is a trade mark that Dassault uses to describe its collection of software. Mr. Bassi unveiled a version of it specific to Solidworks that he called “The first big message of Solidworks World.” It is named 3dExperience.Works and consists of the following programs: • Envoia for planning • Solidworks for designing • Simulia for simulation • Delmia for manufacturing How they work together wasn’t explained. Mr. Charles followed him with the second big announcement of the conference: “Because this noble mission is so significant to make this a better world to live in, we need to expand the possibilities that we offer to you.” He

“We want to make ERP and design easy to use, deploy and exploit in your companies; [Demliaworks] is going to do for the world of ERP what we did with Solidworks,” exclaimed Mr. Charles.

unfortunately confused matters by describing a different kind of 3dExperience.Works. It consists of two programs: • Solidworks • Demliaworks ERP (enterprise resource planning) • ... [The ellipses were in the slide shown the audience]

Demliaworks is a new name for ERP software that Dassault recently acquired from IQMS. About 60 percent of IQMS’ 1,000 customers already were using Solidworks. It’s meant for mid-market manufacturers to make lots of different products, manage their inventory and handle regulatory requirements; it runs

About xShape and xDesign When you see names of Dassault software that begin with ‘x’, you know they are for Solidworks users. I think the ‘x’ is short for “crossover.” In short, you open the Solidworks model in one of these programs, do some modeling around it and then bring the result back to Solidworks. xShape is a new deformable sub-division surface modeler that uses Dassault’s CGM kernel and runs in a Web browser. It is due to ship this summer. xDesign is a solid modeler that also uses Dassault’s CGM modeler in a Web browser. It has been announced for several years in a row and now its Web page finally works, but the software itself remains in beta. If you have a MySolid-

works account, you can apply to test the beta. xDesign isn’t, however, a single program; it is a collection of apps that create 3D designs, manage data, assign tasks to teams and collaborates through the 3DSWYM Community site. Designing with it is very different from Solidworks.

“Not sure if you want an extrude or a revolve? Doesn’t matter with Super features; you can swap back and forth, and even go to a sweep instead if you like,” describes the Solidworks Blog. “Need some help with the shape to get the loads you require? Design Guidance is there to do it the scientific way with a simple stepby-step process. If you are not sure whether you should start a part or an assembly, no problem. xDesign has the flexibility to chop and change at any point in the design and change back again.

There are also no files, so you can rename features, parts or assemblies without the fear of breaking references.”

What’s In Solidworks 2020?

Traditionally, the highlight of Solidworks World occurs on the third day, when staff proudly show off many of the wonderful new features being worked on for the next release. This is when attendees in the huge conference hall go into repeated cheers and applause.

This year, however, Dassault removed the most popular event from the schedule.

The only features shown in Solidworks 2020 were faster operations for loading

models, doing sketches and handling large assemblies.

Dassault Systemes is able to land the world’s largest clients, like aircraft and automotive manufacturers, but not the world’s largest pool of MCAD users.

Dassault software always was designed for the likes of Boeing and Airbus, not the one-man shop.

That’s what Solidworks works well for: The lone designer who spends his time completing relatively uncomplicated parts, never needing the cloud, except for maybe Dropbox. His conceptual design tool is a pencil and paper; his design tool is Solidworks on the desktop; and the machine shop and his customers are local, not global. This is the reality Dassault doesn’t accept, it seems.

Executives display their disconnect by piling emotion on to the “experience” tagline. “And now the topic for years to come is to add emotion, to add the connection between what you deliver to the people, and why people love what you deliver: We call it 3dExperience,” the Dassault CEO told his silent audience. “...because with the 3dExperience, you are going to become story makers. The story will be the experience.”

Today in North America, if you want a job in MCAD design, you most likely need to know Solidworks. It’s a snowball become avalanche, and I worry what Dassault will do next to slow it from gaining more speed.

18 PowerTransmission These cranes at the Port of Virginia move cargo year round, handling roughly 11 percent of the East Coast’s total throughput, even in harsh weather and environmental conditions.

Ship to Shore

Maintenance-free energy chains help drive explosive growth at Port of Virginia.

By Sean McCaskill

T

he Port of Virginia runs a tight production schedule. As one of the busiest ports in the United States – the sixth busiest in the nation, according to data from the Bureau of Transportation Statistics – there is no room for unexpected downtime or costly stoppages for unplanned equipment maintenance. So when the port needed to add cranes to keep up with production demands, the port’s Crane Maintenance Manager, Jeff Johnston, faced a critical decision.

“I was asked: Would you want to go with a wheel festoon system, a motorized festoon system or an energy chain system from igus,’’ Johnston said. “There was no hesitation; no doubt in my mind. We were going to go with igus.”

Danny Webb, general manager of technical support at the Port of Virginia, initially had some doubts about the energy chain, but it didn’t take long to erase those doubts. “Cranes are getting bigger, they’re getting taller, they’re getting faster,” said Webb, who has been working at the Port of Virginia for 33 years.

“It’s impressive to see the amount of technology on one piece of equipment. The biggest surprise to me with the igus system, being a naysayer of chains back in the day, was the reliability.”

Festoon vs. Energy Chains When energy chains were first introduced to the material March/April | 2019

DES_MARCHAPRIL2019_LAZ.indd 18

handling industry, they were considered something of a novelty.

Mobile gantry and ship-to-shore cranes in harbors and ports were primarily equipped with festoon systems to provide power.

Festoon systems include wires or flat cables that carry control and power across a bridge or along a runway or monorail.

Cranes, however, are exposed to harsh weather and environmental conditions. High winds, heavy rains, salt water, snow, sleet and ice can dramatically impact a festoon system. High usage and a strenuous environment cause excess wear and corrosion to the festoon cables and components.

Festoon systems also require frequent inspections, repairs and service to the wheels, trolleys and shock cords. Worn out wheels and bearings, broken trolley saddles and bumpers, snapped shock cords and tangled cables are all examples of the inherent challenges. In fact, over four years, it’s not uncommon to spend about $25,000 in repair for a festoon system, according to a maintenance manager at a port in the United Kingdom.

In contrast, Energy chains aren’t susceptible to the harsh conditions that impact festoon systems. The power and control cables are run through the e-chain in their own partitions, guided and protected at all times.

The e-chain system is then supported by a metal guide trough structure along the entire travel distance. One end of the chain bends into a U-shape and gets connected to the tow arm. The other is fixed and anchored in most applications in the center of the travel within the guide trough. Installing or removing the power or control cable can be done easily and efficiently.

Track Record Maintenance-free components used in energy chains are one of the key characteristics in Johnston’s recommendation to use them in Virginia.

“We were a wheeled festoon port for years,’’ Johnston said. “Bearings, bolts, shock cables, tow cables – all of those components need to be maintained monthly and replaced www.design-engineering.com

quite often. When we switched to the energy chains, all of that stuff goes away.”

Energy chains require only a visual inspection to check for wear or damage to the cable. Festoons can require additional scaffolding or lifts to access the crane’s electrification system, and multiple parts need to be inspected for wear, corrosion or damage.

Energy chains, like this spooled igus plastic “In the first year e-chain, slash maintenance costs over the they were in service, more traditional festoon systems. we were waiting for something major to go wrong,’’ Johnston said. “It just didn’t happen. The maintenance we had to do was minimal compared to the maintenance we had to do with the wheeled festoon systems.”

With its iSense products, igus can reduce downtime even further by providing predictive maintenance capability. These systems can relay to monitoring devices precisely when components need repair or replacement.

Powerful Port The practices at the Port of Virginia are catching the attention of others in the industry. Its container volume increased seven percent from 2016-17 and total tonnage rose 24.4 percent from 2016-17. It handled 11.6 percent of the East Coast’s total throughput in 2016. Just recently the Port of Tacoma took delivery of new STS cranes outfitted with e-chain systems from the factory and Freeport Container Port just completed a revitalization project and are now 100 percent igus on their waterfront.

“The size of the port itself, and the projects we’re undertaking, and the aggressiveness we’re going after is unrivaled,’’ Webb said. “Everybody’s thinking, what’s Virginia doing?”

During a ferocious winter storm in 2016, ports all along the Eastern seaboard of the US had their operation disrupted.

Snow, ice and high winds forced many ports to suspend operations. The Port of Virginia, however, remained operational at full capacity. Reliable and durable energy chains are one of the key reasons why the rough winter weather did not stop operations.

“Having been a customer and partner of the Port of Virginia for 25 years is a statement in and of itself,’’ said John Fornazor, Chief Executive Officer of Fornazor International.

“Looking toward a future of ever-changing container flows, we feel the Port of Virginia will remain a vital export gateway for our cargo.”

F

or almost a half a century St. Catharines-based Canal Marine & Industrial has provided electrical design, engineering and services around the clock to the merchant marine, naval and coastguard fleets in Canada and the rest of the world.

In recent years, Canal has become a leader in the design and supply of marine hybrid power and propulsion systems.

These systems utilize alternative methods for supporting propulsion and the vessel’s electrical power plant, so that fuel consumption and emissions are reduced.

Great Lakes Towing of Cleveland, Ohio (popularly called “The Towing Company”) operates the largest and most experienced U.S.-flag tugboat fleet.

The Towing Company is a significant marine operations link in North America’s U.S. Great Lakes-Saint Lawrence Seaway marine transportation network, an operating area that extends over 8,300 miles of shoreline and roughly 100,000 square miles.

The Marine Integration Group, comprised of Canal Marine with partners Logan Clutch of Cleveland, Ohio and The Breakwater Group of Prince Edward Island, provides Great Lakes Towing with March/April | 2019

state-of-the-art hybrid power and propulsion systems for three new-build tugboats to be operated in the Great Lakes area. These systems allow the vessels to run with their large main engines shut down for extended periods and also allow their diesel generators to run less frequently and more efficiently.

Running into Turbulence Canal faced some challenges developing the hybrid system, which is centered on a common-DC bus arrangement connecting a number of drives, front ends and grid converters.

For one, the air-cooled power converters had to be securely mounted within an environment subject to significant movement and vibration – as anyone who has experienced tugboat operations will testify. The system’s drives, while very efficient, generate some heat which had to be controlled to preserve their rating.

As well as the drives, automation equipment and other electronics had to be mounted in a manner that keeps them accessible, while eliminating the possibility of any electromagnetic interference from drives or motors. Lastly, there are some significant restrictions on the sizing

Tow by Tow To overcome these challenges and provide premium service and high quality products for Great Lakes Towing, Canal turned to Rittal, a company recognized as a proven supplier of enclosures for the marine industry.

“We were pleased to partner with Rittal in developing an integrated solution that provided security, flexibility and reliability, so that Great Lakes Towing can rest assured that their tugboats can run efficiently and in an eco-friendly manner,” says Shawn Balding, Director, Canal Marine & Industrial. “This is the first of three Hybrid Systems for The Great Lakes Towing Company to kick off in 2019, and we hope to continue our partnership that works well for all of us.”

Indeed, Canal personnel have extensive experience working with Rittal products over the past ten years. Canal personnel have installed drives rated above 1MW within Rittal TS8 enclosures in recent years. Rittal’s products are considered, within the marine industry, to be sufficiently robust and flexible for use in a range of applications; from small bulkhead-mounted control boxes to full switchboards, MCCs and drive lineups.

As a result of the partnership with Rittal, Canal Marine & Industrial was able to deliver a flexible system where modular enclosures could be connected, or ‘bayed,’ to create a longer enclosure perfectly matching their needs.

In addition, the system employs a common bus-bar system complete with clamps, connectors, covers and other accessories. Not only does this remove the task of designing a solution in-house, it also provides a rated (documented) system suitable for their steady state currents and braced for their peak fault currents.

Also, the system’s fans, heaters and thermostats allow Canal Marine to ensure www.design-engineering.com

2019-04-10 1:56 PM

InsideDesign 25 the environment within the enclosure is regulated. During periods of down-time, the enclosure is heated to prevent condensation. While in use, fans are used to remove heat produced by drives and other components. The Rittal fans move a significant amount of air, as the ambient temperature in the tugboat is already elevated by the presence of large engines.

Rittal’s modular system allows Canal Marine to individually purchase infrastructure, such as side panels or additional supports, to tailor the enclosure perfectly to their needs. Rittal even provides cable-management accessories that help maximize the internal space, keeping the cabinet line-up as small as possible. Replacement elements – like doors or side panels – can be purchased individually to accommodate rework needed for future upgrades to the hybrid system.

“If state-of-the-art technology in industry can help toward sustainable environmental management and protection, then that is a good thing,” says Rittal President, Tim Rourke. Shawn

DES_MARCHAPRIL2019_LAZ.indd 25

Protected by a Rittal custom enclosure, the components in Canal Marine & Industrial’s compact hybrid system share a common bus-bar and are temperature controlled to heat or remove heat from the enclosure as conditions dictate.

Balding, Canal Marine’s Director adds, “Our goal is to provide our clients like Great Lakes Towing with solutions that are energy efficient and environmentally friendly, and Rittal complies in every way.”

“In the ‘maritime applications’ segment, Rittal is pleased to offer a range of complete system solutions that are sufficiently robust to reliably withstand stringent demands, including systems for particular environmental requirements, resistance to vibrations and seawater, and products with special approvals, which

are important for maritime applications,” says Tim Rourke, President of Rittal Systems Ltd. “We were so pleased to partner with Canal Marine to offer solutions that incorporate the vast product diversity of Rittal’s standard range, flexibly combined with one another for considerable safety and reliability as well as time and cost savings”.

Festo Unveils Latest Bionics Projects German automation company’s BionicSoftHand, BionicSoftArm and BionicFinWave pneumatic robots juiced by artificial intelligence.

A

s has become a tradition in the automation world, Festo revealed its latest pneumatically driven robots at Hannover Messe 2019. Most years, the automation company debuts a mechanical animal, such as last year’s bat-like BionicFlyFox and 2017’s OctopusGripper. This year, however, Festo pushed the BionicSoftHand and BionicSoftArm, a human-like pneu-

matically-driven hand and an arm, both designed to work in close collaboration with human workers.

In line with the cobot and soft robotics concepts, Festo’s BionicSoftHand doesn’t have bones. Instead, its fingers consist of flexible bellows structures – air chambers wrapped in a 3D textile knitted from high-strength, elastic threads. Varying the weave of the fabric makes it possible to control where the structure expands and where it doesn’t. As a result, the humanlike fingers are flexible, adaptive and sensitive, but still capable of exerting strong forces, the company says.

Rather than weigh the BionicSoftHand down with servo motors, the designers developed a digitally controlled pneumatic valve terminal mounted directly on the hand. This allows each finger to be supplied by a short air tube from the “wrist” and controlled by proportional piezo valves while the overall system is supplied by a single air tube through the arm.

For control, Festo has paired the robotic hand with an AI routine that learns by trial and error. Instead of imitating a specific action, the hand is given a goal, which it gets progressively nearer to accomplishing through positive and negative feedback. Sensors at its finger tips and “knuckles” provide the necessary tactile feedback. As a demo, the BionicSoftHand was tasked with rotating a 12-sided cube so that a particular face points upwards by the end of the task. The movement necessary to complete the task is taught virtually to the robot-hand’s digital twin with assistance from 3D depth sensing cameras.

While not a companion to the hand, Festo’s BionicSoftArm follows the same design principles. The cobot’s modular elephant-trunk-like design allows for up to seven pneumatic bellows segments and rotary drives. According to the company,

FluidPower:News 35 this gives the arm flexible reach and mobility. It can be fitted with range of Festo grippers, depending on the application. The soft bellows also allow it to operate in the same space as people, eliminating the need for safety cages or light barriers.

Lastly, Festo did unveil a new robotic animal, the BionicFinWave, that takes its inspiration from the way that the fins on cuttlefish and aquatic flatworms undulate, rather than flap, to propel them through the water. This principle allows the BionicFinWave to maneuver forwards or backwards through an acrylic tube system.

The BionicFinWave robot’s side fins are cast out of silicone and don’t require struts or other supporting elements. The two fins are attached to the left and right of nine small lever arms, which in turn are powered by two servo motors. Two adjacent crankshafts transmit the force to the levers so that the two fins can be moved individually to generate different shaft patterns.

The undulating fins are particularly suitable for slow and precise locomotion.

A cardan joint is located between each lever segment to ensure that the crankshafts are flexible. For this purpose, the crankshafts including the joints and the connecting rod are made of plastic in one piece using the 3D printing process.

The remaining elements in the BionicFinWave’s body are also 3D-printed, which enables its complex geometries in the first place. With their cavities, they act as flotation units. At the same time, the entire control and regulation technology are watertight, safely installed and synchronized in a very tight space. www.festo.com

FluidPower:Pneumatics

PNEUMATICS OR ELECTRICS? Important criteria to consider when choosing technology.

M

achine manufacturers generally have a choice of different pneumatic and electromechanical automation solutions when implementing an automation task.

However, there is no general advice on when the different technologies are typically used.

As a result, the user is frequently faced with the question of which automation technology is best suited, technically and economically, to their individual requirements.

Criteria like dynamic response, force, control characteristics, load stiffness and above all economic efficiency always play an important role when making this decision.

Positions and Drives Electric actuators come in many different versions. As a rule, the motor’s rotary motion is converted into a linear motion by a mechanical system. There are also electric direct drives that can generate a linear motion without any additional mechanical system. In practice, spindle and toothed belt drives are the most widely used linear drives.

Pneumatic drives have no such separation. The mechanical system of a pneumatic cylinder also executes the drive function. This means that pneumatic drives need much less space, making them suitable for applications where space plays a central role.

Many industrial applications require cyclical travel between two defined points. This is a typical case for using pneumatic drives because of their ability to carry out a simple point-to-point motion with little effort.

If more than two or three positions are to be approached, electric drive systems are often used. These systems can approach an almost unlimited number of intermediate positions and can thus also realize more complex motion sequences.

March/April | 2019

DES_MARCHAPRIL2019_LAZ.indd 36

Dynamic response, force or both?

Depending on their design, electric drives can generate both high dynamic responses and high forces. They even outperform their pneumatic counterparts under extreme conditions. This is due to the different mechanical gear ratios; however, this does result in a direct correlation between dynamic response and force.

What this means is that high forces, for example, can only be realized at the cost of the dynamic response (and vice versa).

Spindle drives, for example, are particularly suitable for high forces at low to medium speeds, while toothed belt drives offer high dynamic response at the cost of maximum force.

When looking at dynamic response and force separately, the performance values of pneumatic drives are not as high as that of electric drives. Their ratio of force to dynamic response, though, is outstanding in many applications and superior to that of electric drives, especially in relation to installation space. That is why pneumatics is well suited to applications requiring high performance density.

Basically, linear motion processes can be divided into two phases: The motion itself and the holding phase at the end of the stroke. The importance of a component within the overall task can also be an

indication as to which drive technology is most suitable. While pure motion tasks are executed very efficiently by electric drives, the technical operating principle of pneumatic drives makes them perfect for applying continuous forces and maintaining them for any length of time. This makes pneumatics the first choice for high continuous forces or long holding times.

Electric drives are normally used if an application requires free positioning or special acceleration sequences and speeds.

Due to their control characteristics, they can be flexibly adapted to a wide range of requirements. Unlike standard pneumatics, they can also approach an unlimited number of intermediate positions.

Servo-pneumatics is an alternative if compressed air is to be used for a specific purpose, for example EMC or explosion protection. By having a displacement encoder, a proportional valve and a position controller, servo-pneumatics is a controlled system with which free positioning and detailed motion profiles can be achieved.

Load stiffness or flexibility?

In addition to special motion profiles, an application may also need high load stiffness or a deliberately flexible system. Since electric positioning drives are generally operated in closed-loop mode, they respond www.design-engineering.com

YOUR EXPERT SOURCE FOR

ENCODERS immediately to deviations in the required behavior and make the necessary adjustments. Despite additional external loads, electric drives therefore generally follow their specified trajectory.

Pneumatic drives, on the other hand, can respond flexibly to external influences, even with high continuous forces and can usually handle even overloading without any damaging effects. This characteristic can also absorb shock or impact loads that would impair other drive types.

One of the main differences between pneumatic and electric drive technology is the actual system setup and the associated complexity. Pneumatic systems have a simple setup and are easy to install, commission, operate and maintain.

While electric systems have been stateof-the-art for decades, they are unquestionably more complicated and require specialized staff with a higher level of technical knowledge. This is an important consideration for the plant manufacturer, but also for the customer who will have to operate and maintain the plant.

Economic comparison Last but not least, the economic efficiency of a solution is also of great importance.

An analysis of the procurement costs reveals that pneumatic solutions generally require much less investment than electric solutions. In addition, pneumatics are quick and easy to set up and commission.

However, the operating costs must also be taken into account. Energy costs often constitute a key part of a system’s total cost of ownership. Electric drives are an energy-efficient option, especially for tasks involving just motion. Their energy con-

sumption is also load-dependent.

Compressed air, on the other hand, is often perceived as being a relatively expensive form of energy. But very few customers know the (absolute) energy consumption of their pneumatic actuators.

This means they don’t have the data needed to discern if an alternative solution could be more economical. Another challenge is ensuring that pneumatic systems are correctly used and sized, as these factors are also key to their efficient use.

The EnEffAH research project completed in 2012 (“Energy Efficiency in Production in the Drive and Handling Technology Field”, a joint project as part of the German Federal Government’s 5th and 6th energy research programme) provides a simple guide to the efficiency of an electric or pneumatic drive system.

It clearly shows that electric drives are very efficient when it comes to large strokes with short holding times, while pneumatics is the preferred option for short strokes combined with holding tasks.

The question about which technology is more economical therefore depends on the application. However, basic trends about the efficiency of drives are often also applicable to their economic efficiency.

Only a detailed investigation that considers the specific operating conditions can provide a clear and reliable answer to the question as to which technology is best.

The decision for or against a technology is based on several criteria, only some of which are examined here. Given the clear differences between pneumatics and electrics, it is not possible to make general statements about which technology is best.

It is therefore important to focus on the problem and the associated parameters before choosing the most suitable solution. That is the only way to find the best technical and most economical solution.

FLUID POWER

Roudtable 2019

Canadian fluid power leaders discuss the impact of IIoT and the challenges the industry faces.

How has business been in the last year?

Don McCrudden, VP Business Development, Festo Canada: Our business continues to flourish and has done for quite some time now. The one proviso is that, when I look at Festo’s business, it’s made up of three business units: Process automation, electrical automation and pneumatics. When we look at our broad based business, our pneumatic business is great but has nowhere near the growth of the other two. In part, that’s because process and electrical automation are starting out at a much lower baseline. Pneumatics is single digit growth but significant. Process and electrical have much faster growth but have a long way to go to catch up with our pneumatics business.

Campbell Tourgis, Vice President, Wainbee: Looking at 2018, based on the

success of our customers and suppliers, it was our busiest and most fruitful year on record. We experienced a tremendous project resurgence that started about 18 months ago. Most of these initiatives were for productivity enhancement and capital equipment projects. We feel that was a result of the world economy expansion that provided our OEMs with an initiative to stock more and build faster. Unusually though, we had our best year ever in the span of 10 months. Come November, the industrial sector took a pause. Our assessment is that, by November, people were tired from a busy year and budgets had been spent. Those factors combined with a momentary collapse in various stock markets at year-end due to uncertainty around NAFTA and other political strife, lead to this year-end slow down. Our analysis suggests that, by mid-January, a level of normality has resurfaced.

Frank Pirri, Sales and Product Manager, Flodraulic Group Canada: Flodraulic ended 2018 well above forecast and 2019, thus far at least, doesn’t show any signs of slowing down. I can credit this to the introduction of a few new specialty products as well as our business model as a systems integrator. Ideally, we like to work with our customers, from the prototyping stage to production. That allows us to provide a complete package that includes the hydraulic components as well as the electronics to control them. With that approach, we have been expanding our current business with our existing customers while attracting new ones.

Rob Chin, Sales Manager, MP Filtri Canada: 2018 was a very good year that well exceeded our forecasts. For us, this was a result of a strong Canadian economy in most sectors supported by our wide

The hottest trend isn’t so much a product as it is the services that support the products. For us, that’s the integration of pneumatic, electrical and mechanical...This kind of integration isn’t just a Festo trend; it has become standard in the industry.

range of products, which are heavily stocked at our Canadian warehouse for immediate delivery. This year started off strong, meeting our growth forecasts; however, some of our customers are expecting business to soften for the second half.

Which products or product categories are popular at the moment?

McCrudden-Festo: The hottest trend isn’t so much a product as it is the services that support the products. For us, that’s the

integration of pneumatic, electrical and mechanical. For example, if I roll the clock back, we wouldn’t have sold any pneumatic actuators with a mechanical bearing. Today, expressed in dollars, probably 50 percent of our pneumatic actuator business includes a mechanical bearing.

Previously, customers had to find a bearing supplier, hunt through part catalogs, align the bearing, etc. Now, they can buy the same integrated device from one supplier. It’s a similar story for the electrical integration. We’ve really been

pushing valve terminals with electrics on one side and pneumatics on the other.

The upside there is you don’t have to mount and wire a third party I/O device and you only have to mount one thing rather than five. This kind of integration isn’t just a Festo trend; it has become standard in the industry.

Tourgis-Wainbee: For Wainbee, the future trend is different than the industries we achieved growth in for 2018.

We’ve participated in a tremendous

40 FluidPower:Roundtable The biggest trend we’re seeing is a demand for more system integration in that our customers are looking for a complete package...We are finding that, as our customers’ employees retire, they are having a harder time filling those positions and so they depend more on companies like ours.

– Frank Pirri, Sales and Product Manager, Flodraulic Group Canada increase for R&D investment in electric vehicle integration to hydraulics. People are looking to get away from diesel power in these market segments and into using cleaner alternatives. That trend really took hold in 2018. That presents opportunities and challenges for a company like ours in the sense of helping our customers facilitate battery management with hydraulic control. Our success last year, however, was driven by core motion control products enhanced by IIoT concepts that people now understand help optimize productivity.

Pirri-Flodraulic: The biggest trend we see is a demand for more system integration. Our customers are looking for a complete package. We’re finding that, as our customers’ employees retire, they are having a harder time filling those positions and so they depend more on companies like ours. Even those who were more independent are now increasingly leaning on us for support. In part, it may be that the technology is evolving at a quicker pace, especially now that electronics in fluid power has come on so strong. Currently, Flodraulic has 12 in-house programmers to accommodate the demand.

Chin-MP Filtri: Modern hydraulic components are being built to much tighter tolerances to improve efficiency and performance, which is creating a strong demand for hydraulic filters and oil contamination monitoring products. Hydraulic components gain efficiency and performance by reducing internal tolerances. Without clean oil, it’s not possible to reliably reduce internal tolerances. By monitoring contamination, it’s possible March/April | 2019

DES_MARCHAPRIL2019_LAZ.indd 40

to identify problem areas well in advanced of a costly contamination related failure.

What do you feel are the major challenges facing the industry presently?

McCrudden-Festo: One challenge facing the industry is that the upfront cost of electrical motion is dropping. As it stands now, building with pneumatics makes for a less expensive machine for the end user, in the same way a fuel-burning car is less expensive than a Tesla. But, as the cost of electrics decreases, there’s no question pneumatic motion will be converted to electrical to take advantage of its inherent advantages. On the other side of the coin, the degree of automation on any piece of equipment is going up quickly as well and therefore the market size is growing. So if the rate of automation is growing faster than the rate at which electrics is eroding pneumatics, then it’s still growing.

Tourgis-Wainbee: The major challenge is what’s referred to as the talent drought.

The industry is busy right now, so I think most would say that finding good talent is tough. But that’s too easy an answer. Really, I think the fluid power world hasn’t done a good enough job promoting itself as leading edge and an industry one can build a career around. So convincing those with talent (and everyone has a talent) that their potential is best served in the fluid power industry is the real challenge.

Pirri-Flodraulic: One of the biggest challenges still is finding qualified people.

Unfortunately, fluid power is not a recognized industry by the general public.

Very few middle school or secondary school students know it’s a career path

option. I myself only stumbled into it by chance when high school teacher of mine suggested it. I think that there is a huge perception problem. People don’t seem to realize fluid power contributes to their everyday lives. Through the Canadian Fluid Power Association, we are aiming to change this lack of awareness. One way is by encouraging students to participate in our annual Fluid Power Challenges, with the hope this exposure will encourag them to choose a career in fluid power.

Chin-MP Filtri: The hydraulic industry in particular is constantly being challenged by new technologies that didn’t exist or weren’t competitive in the past, such as variable frequency drives. VFD motors, when used on hydraulic power units, are great for improving the overall efficiency of the hydraulic unit. However, when VFDs are combined with mechanical drives/gear boxes, they can offer a complete alternative to hydraulic systems that was not possible in the past.

How might Industry 4.0/IIoT impact fluid power in the future?

McCrudden-Festo: It’s hard to say. IIoT/ Industry 4.0 comes down to capturing big data, electronically. For Festo, which has pioneered the marriage between pneumatics and electrics, the impact will be large.

We already have the electronics in our pneumatic components to take big data from. With that, you can monitor parameters like changes in air consumption and other metrics that maintenance staff can use to pinpoint when and where a machine needs overhaul. For companies that don’t have that technology built-in are stuck. For them, Industry 4.0 will have little impact. www.design-engineering.com

FluidPower:Roundtable 41 The hydraulic industry in particular is constantly being challenged by new technologies that didn’t exist or weren’t competitive in the past.

– Rob Chin, Sales Manager, MP Filtri Canada

Tourgis-Wainbee: IIoT is really just a progression of the original industrial revolution; a new name for something that already existed. Still, I see it having a tremendous impact for fluid power. It’s natural for people to make decisions based on feelings, but too often we defend those decisions anecdotally without evidence. I think what IIoT/Industry 4.0 brings is the ability to trust our feelings through the backup of empirical data.

Pirri-Flodraulic: From the mobile hydrau-

lic side of things, it has and will continue to have significant impact. Use of a variety of sensors, you can remotely monitor pressures, temperatures, speeds and a host of other parameters necessary for proper machine operation and control. With that information, you can perform preventative maintenance and remote troubleshooting, as well as geo-fence equipment to prevent loss, monitor equipment to make sure it is not being abused and monitor productivity. IIoT is already having a large impact on the industry and will only increase as

these machines become smarter and are increasingly connected to the Internet.

Chin-MP Filtri: We expect our contamination monitoring products will play a significant role in hydraulic systems that integrate with Industry 4.0. Considering that 80 percent of failures are contamination related, we believe that customers will see the value in monitoring their systems for contamination as part of their cyber-physical Industry 4.0 requirements.

Digitizing Fluid Power IIoT-enabled fluid power solutions hold promise of new business models while shoring up weaknesses.

•

G

iven its flexibility, low up-front costs and unrivaled power density, it’s no surprise fluid power remains a major motion control technology globally.

According to market analysis by Frost & Sullivan, the total hydraulic and pneumatic equipment market totalled $52.67 billion in 2018, roughly 76 percent of which is hydraulic business and 24 percent pneumatic.

Europe, the Middle East and Africa accounted for the largest share of that total revenue at approximately 40 percent, followed by North America (~30 percent), Asia Pacific (just under 25 percent) and Latin America (~6 percent). Market share leaders include Bosch Rexroth and Parker Hannifin tied for the top spot followed

by SMC, Eaton and Festo.

For all its market strength, however, the industry faces a number of on going challenges. Foremost among them is the steady electrification of formerly fluid power industrial applications. For many end users and system integrators, electric represents a cleaner and more efficient solution with a lower maintenance cost.

Other challenges, the market analysis firm contends, include a shortage of skilled workers in the field and the penetration of low cost fluid power components from regions with low manufacturing costs.

To address these challenges, the market research firm says IIoT technology represents the industry’s best strategy to overcome fluid power’s perceived weaknesses and open new business models. The most obvious application of the digital transformation is improved maintenance.

“Digital troubleshooting saves time, expense and effort,” said Frost & Sullivan Industrial Research Analyst, Varun Raman, in a recent webcast produced by March/April | 2019

V o the market analysis firm. “With efficiency being the biggest problem for fluid power systems, the energy savings that each plant has reported by using smart fluid power technologies, is an improvement of 20 to 30 percent in many cases.”

In addition, Raman said, digitization also streamlines service requests. Rather than a potentially lengthy and costly distributor-driven model, factory and mobile level analytics allow service requests to be placed only when absolutely necessary. It also simplifies maintenance in that shutdowns can be planned while at the same time improving productivity because of minimized unscheduled downtime.

Beyond preventive maintenance advantages, the market analysis firm argues that digitization also opens new business models. While fluid power components have become a commodity susceptible to low price wars that drive down margins, digitization allows OEMs to differentiate their product and introduce a more service-oriented offering.

“Some of the emerging business models we see involve a shift from a purely

fixed product-driven business to more services and also outcome driven models,” Raman said. “We see that having implications for how fluid power services will transform over the next five to 10 years.”

Specifically, Raman recommends suppliers move toward a subscription/ outcome-based model. Rather than a single sale, such a strategy allows the OEM to follow up with the end user over time. As well, service pricing is driven by outcomes or reaching specific goals, helping suppliers stand out from competitors on more than simply component costs. For the integrator, digitization opens subscription-based remote machine monitoring and data analysis rather than a single machine sale model.

“Fluid power is no longer going to be just a hardware component industry where prices are constantly being driven down by commoditization and competition from low labor cost manufacturers,” Raman said. “Predictive analytics and the software side will create opportunities for a recurring revenue stream.”

FluidPower:Showcase 45 Gradient Valves

Clippard released its NIV series of gradient valves that feature multiple 2-way, normally-closed solenoids connected around a central body. According to the company, this design provides a reduction in internal volume with enhanced mixing capabilities. Each actuator operates independently, allowing for flow of various media to be mixed or for one media to be split into multiple streams. These bidirectional compact valves also feature PTFE coating in all wetted areas, low power consumption, high cycle life and fast response time. www.clippard.com

Mini-slide

Festo’s launched its DGST series, a pneumatic mini-slide line with the smallest footprint on the market, the company says.

The unit’s slide and yoke are manufactured as a single component, contributing to rigidity and perpendicularity. The minislide also features a backlash-free yoke connection and recirculating ball bearing guide. The series comprises seven sizes from 6 to 25, and variants are available with stroke lengths from 10mm to 200mm. Two DGST drives can be joined in several possible combinations, without adapter plates. All interfaces are symmetrical, and all supply port connections are on one side of the unit.

Proximity sensors can be integrated into the body of the minislide, so there are no projecting parts. The DGST series comes with a choice of three cushioning types: Elastic cushioning with or without end-position adjustment or self-adjusting shock absorbers with end-position adjustment.

dardized electronic nameplate of plug & play devices reduces machine and system standstill. Components are identified via site ID and electronic nameplate for replacement. Parameterization is carried out automatically by the IO-Link Master without any need for action by the technician. www.boschrexroth.com

Hydraulic Chain

igus introduced its E2 hydraulic chain that guides two hydraulic hoses in addition to power and control cables to prevent torsion and bending of the hoses through a predefined minimum bend radius. For the E2/000 series, a one-piece, solid extender crossbar design and the heavy-duty pin/bore connection ensure high strength, even for large unsupported lengths. The hydraulic chain has an external width of 41.2mm and an external height of 57.5mm. The predefined minimum bend radius is 75mm. The total required installation height for the chain is 255mm. Thus, the E2 hydraulic chain can be integrated into almost any application, such as close to the base or on the side wall of support legs, a concrete pump or a mobile crane. www.igus.com
