Abstract - Connecting rods are used to transmit the gas
the underlying portrayal to the last outcome, you make a 3d model. From this model, you can make 2d drawing or mix segments comprising of parts or subassemblies to make 3d gatherings. You can likewise make 2d illustrations of 3d assemblies. When planning a model utilizing solidworks, you can picture it in three measurements, the way the model exists once it is fabricated.
pressure which is acting on the piston to the crank shaft. It acts as a rigid link. It is in kinetic motion so chances of distortion in connecting rods were high when compared to other engine parts. In this research work, the basic design of connecting rod of 4 stroke petrol engine i.e. Splendor is made with the help of SOLIDWORKS 2015 and then finite element analysis is performed with the help of ANSYS WORKBENCH 13.0 software. In this analysis 2 different materials were taken into consideration. First one is conventional AISI 1070 steel and second one is AISI 4337 steel. By the analysis values of stresses, strain, factor of safety in connecting rod were obtained in both the materials and compared with each other. In this research various types of failures, their cause were discussed. The analysis result shows safe design of connecting rod under given conditions so that maintenance actions can be minimized.
ANSYS Workbench is typically called a project-management tool. All our software tools can be linked using this top level interface. The passing of data between ANSYS Geometry, mesh, solver, Post processing tools is handled by the workbench. The individual applications and passing of the data between them is done and managed by Workbench. It makes it easy to automatically perform design studies, parametric analyses, etc. For design optimization.
2. LITERATURE REVIEW
Key Words: Connecting rod, petrol engine, ansys, solidworks.
Internal Combustion(IC) engine has comprised of numerous parts like cylinder, piston, crank and connecting rod. One of the fundamental pieces of an engine is the connecting rod. To transmit the reciprocating movement of the piston to rotary movement of the crankshaft is the main function of the connecting rod. Connecting rod has piston end and also crank end. Piston is connected with the piston end. The crank end (huge end) is appended to the crankshaft. The connecting rod should be designed so that it can withstand the load with no failure amid high cycle fatigue. The most significant pieces of connecting rod are crank end, long shank and piston end. There are various reasons due to which a connecting rod fails, some of which are – less lubrication and heat, overloading the rods, elongated rod bore, bore stretch, fatigue, pin failure, over revving, hydrolock, failure of bearing and wear & tear.
G. Naga et al. [1] explains weight optimization in the connecting rod of the IC engine by various materials like Genetic steel, aluminum, titanium and cast iron. The model connecting rod is made on Pro-E and analysis is done on ANSYS. They carry out the various load analysis in static and stress analysis of the connecting rod. Design optimization for appropriate material to minimize the deflection. The load acting on the connecting rod as a function of time are obtained. The relation for obtain the load for the connecting rod at the given constant speed of crankshaft is also determined. They find out that the connecting rod can be designed and optimized under a tensile load corresponding to 3600 crank angles at the maximum engine speed as one extreme load and the crank pressure as the other extreme load which result to cost reduction and weight reduction. The bending stresses are calculated for tensile bending stresses about 266.86333 N/mm2 and also found that connecting rod made up of genetic steel shows less deformation and stress then titanium, cast iron and Aluminium.
Solidworks is a strong solid modeling PC helped structure (cad) and PC supported building (cae) PC program that keeps running on microsoft windows. Solidworks is disseminated by dassault framework systems. In this examination and analysis solidworks 2013software programming is utilized to make a 3 solidworks using a 3d configuration methodology. As you structure a section, from
Nikhil et al. [2] in their study the material of connecting rod is replaced by aluminum (Al 360) based composite material reinforced with silicon carbide and fly ash and they also describe the model and analysis of connecting rod. FEA analysis was done on two materials of 180cc engine connecting rod. They take parameters like von misses stress and deformation was obtained from ANSYS software.
