A connecting rod is subjected to many millions of repetitive cyclic loadings.Therefore, durability of this component is of critical importance. It is necessary toinvestigate finite element modeling techniques, optimization techniques and new designto reduce the weight at the same time increase the strength of the connecting rod itself.Shenoy (2004) was explored the weight and cost reduction opportunities for a production forged steel connecting rod. The study has dealt with two parts which aredynamic load and quasi-dynamic stress analysis of the connecting rod, and second tooptimize the weight and cost. Shenoy and Fatemi (2005) were explained aboutoptimization study was performed on a steel forged connecting rod with a considerationfor improvement in weight and production cost. Weight reduction was achieved byusing an iterative procedure. In this study weight optimization is performed under acyclic load comprising dynamic tensile load and static compressive load as the twoextreme loads. Yang et al. (1992) describes a successful process for performingcomponent shape optimization should be focused on design modeling issues. A modular software system is described and some of the modules are widely available commercial programs such as MSC/PATRAN and MSC NASTRAN. The upper end (pin end) of aconnecting rod is optimized under a variety of initial assumptions to illustrate the use of the system. The objectives of the study are to develop structural modeling of connectingrod and perform finite element analysis of connecting rod. The main objective is todevelop topology optimization model of connecting rod.
