Static Stress and Thermal Analysis of Connecting Rod using FE-Analysis 2018-32-0034
In series of automobile engine, in running conditions, different components of engine undergoes static and dynamic loadings. While one of the main component known as connecting rod is used to convert linear motion of the piston to reciprocating motion of the crankshaft. In this paper, a comparison study on connecting rods made up of 42CrMo4 Alloy Steel (Forged steel) and 7075-T6 (SN) Aluminium Alloy is conducted to analyses the static and thermal stress, using the Finite Element Analysis (FEA). The main advantage of FEA is Virtual testing, it saves time and money. After measuring the dimension of connecting rod, the CAD model is developed in Solidworks software and imported to Solidworks Simulation software. Static stress analysis is done by fixing the crank end and the load is applied at the piston end of connecting rod and vice-versa. Maximum stress point and section prone to failure is found out by this analysis. Also, the thermal analysis of the connecting rod is performed. The purpose of this study is to show the performance of connecting rod under different loading condition with considerable reduction in weight keeping the F.O.S (Factor of safety) always greater than 1 to resist the failure.
