Formula Student China GreenTeam Uni Stuttgart e.V. Season 2013 Report



ear Sponsors, Supporters and Friends of the GreenTeam,

its done! About three weeks after the competition in China we are safe and sound back to Stuttgart. The time in Far East was exciting and demanding, but it was worthwhile: we won! Also beside the competition we could network with the other teams and experienced an uninhibited hospitality and helpfulness. But please, enjoy reading all details about our trip on the following pages. We look forward to your thoughts and feedback! On behalf of the GreenTeam, Axel Leins

Formula Student China The Formula Student China exists now since three years. In cooperation with the Society of Automotive Engineers of China (SAEC) the first competition could be held in 2010. The organziers are very motivated to professionalize the event and let it grow. For example, we could get to know to a delegation from China in Silverstone. They traveled to UK to gain impressions. Since 2012 the competition was open for electric cars, but first only for Chinese teams, there the GreenTeam participated without unofficially. On from this year, it was possible for non-chinese

teams to participate officially. The most important change is the new venue. Up to this year the FSC took place in Shanghai at the Formula 1-course. For 2013 and the following years they decided on moving to Xiangyang (Hubei), about 1000km in distance from Peking and Shanghai and built a complete new race track for the Formula Student.

The team for China The tasks are related to the Season 2013.

These 16 team members make the team for the competition in China.

Report PREPARATION 12.10.-14.10.

Already the arrival in Xiangyang was an adventure – due to too much smog, the aircraft spent about 20 minutes in a holding pattern until they decided to have a refueling stop at Wuhan. We then arrived with a 2hours delay in Xiangyang. Xiangyang is as large as the half of Baden-Württemberg, On the way to the hotel there are construction sites as far as the eye can see – Xiangyang is a typical “boom town”. The competition site was planned until spring 2013 and had been built up in just 6 months, a remarkable performance. The course is also built for kart races. Our race car was sent of from Stuttgart in a cargo box, which arrived in Xiangyang in a typical sea container. Somehow we began to wonder in the way the customs duty in Beijing treated the box. Neither the box had been fully closed, nor has the load in the box been saved again. Well, to our luck nothing happened... Because the accumulator cells are declared as dangerous goods, so the accumulator had to be disassembled in Germany and assambled in China, which took about 2 days. In the following days more and more teams arrived in Xiangyang. Different to their plans, the teams from Liverpool and Gothenburg were not able to participate, so we should remain as the only non-chinese team.

▲ The cargo box and the sea container

▲ The Xiangyang Airport. Tiny compared to the big city

▲ Quite high interest on from the first minute

Report Day 1 – Registration 14th October

On the first official day there was only the team registration, but because of several import regulations we had to organize things like fire extinguishers and tape. The Chinese welcomed us warmly and the interest in the team and the car was quite high. Already on the second day the local newspaper of Xiangyang gave a report, after which some TV companies requested for interviews.

Day 2 – Scrutineering, Statics 15. October

The FSC organizers had a very ambitious time planning. The Scrutineering as well as the whole Statics were planned at only one single day (50 teams). Fortunately we needed not too much preparation time – after 4 competitions, the Statics as well as the Scrutineering went quite well. But: the language barrier (written or spoken) became a central point and could be only solved by our Chinese team members working as translators. So the Statics/Scrutineering took much longer as scheduled. Also, the Scrutineering was accompanied by a media team to gain experience. One of the most experienced Electrical Scrutineers, Jürgen Falb, also came to the competition and could give good advice to the Scrutineers.

Report Day 3 – Scrutineering, Dynamics 16th October

This day started with about 2 hours of queuing - their time planning did not work out. Too less teams passed Scrutineering yesterday, eventually the operations became more hectic (and sometimes chaotic). The organizers decided on reforming the entrance for Scrutineering which let the crowd being like in a big funnel. Nevertheless we had patience and finally passed rain-, tilt-, and braketest. After the lunch break – being supplied by local deliveries – we went on with Skid Pad and Acceleration. The scoring for Electric cars was separated to the Combustion scoring, so we had to compete against 9 E-Teams. SkidPad Max 5,260s – best time 1st place Acceleration (0-75m) Daniel 3,363s - best time (and our best accel-time this season!) 1st place

▲ Skid Pad

▲ Finishing Acceleration - best result of the season with 3,363s

Report Day 4 – Dynamics 17th October

Imporant visitors today! The President of the University of Stuttgart, Prof. Wolfram Ressel, stopped in Xiangyang to visit us. Together with Prof. Wiedemann, who arrived yesterday, we got together with interesting personalites – e.g. the Vice President of the SAE China, Mr. Yen, or the Vice President of the Beijing Institute of Technology. Along to these official meetings the competition we went on with the competition – we passed Autocross with best time! Hua Ai and Andreas Pilsl were able to drive these best times despite they had nearly no possibility for testing Autocross with the E4. The preparation time between Italy and departure of the cargo box for China was too short. Our usual Autocross- and Endurance drivers, Stephan Klatt and Peter Suess, were not able to come to China due to proffesional duties. Autocros Andreas Pilsl 62,5s Hua Ai 59,2s (Bestzeit) 1st place

Report Day 5 – Dynamics 18th October

Now it became quite thrilling – the next competitor had about 100pts less than us, the Endurance should decide on the 1st place for us. Of course we knew about the reliability from Austria and Italy, but always had the “did not finish“ from Silverstone and Hockenheim at the back of our minds. The E4 started as last and drove with steady times, the last five laps it was the only race car on the track. Of course there was some melancholy upcoming –this should be the last official participation of the E4 in this season... Hua and Andreas drove good times without exception. Despite the used power was only a part of the allowed power we drove best times (also against a Formula 2 driver in a combustion car!). Afterwards there was the big group photo and the award ceremony - unfortunately in Chinese only. But: we were honored for two things. 1st Place Electric Overall 1st Place “Lightweight Award“. This was now our first international success – and we are very proud of it. Unlike at European competitions there was no final party for the teams, but we made it up at the following evening. Directly after the competition we first had to pack the cargo box for the delivery to Germany.

Colloquium at the Tongji 22th October 2013

Since 1994 the Univeristy of Stuttgart stands in cooperation with the Tongji University, Shanghai. A special step was a double master‘s degree program for the course of studies “Automotive Engineering“ and “Mechanical Engineering“ in Summer of 2012. With our participation at FSC2012 we could operate for the University of Stuttgart on the level of the Formula Student –with workshops for the Formula Student team of the Tongji–University. This team planned their first Formula Student Electric race car. Also in this year we were engaged at the Tongji-University. After the competition, most of the team members took the journey to Shanghai for a Colloquium at the Tongji University. There were both teams, E and C, from the Tongji, as well as the professors Zhang, Xiong and Wiedemann. The patronage was by ZF Friedrichshafen AG. ZF is involved in the Tongji University, in the University of Stuttgart and in the GreenTeam. The Colloquium was quite interesting – every team presented details about its race car. Afterwards, at a round table, there was a discussion about topics concerning the Formula Student with teams and professors. Also Dr. Gall, Head of the ZF Engineering Center Shanghai, presented interesting insights into the Chinese Market and how ZF is involved.
