Abstract: In order to obtain a sufficient strength and light weight connecting rod of a engine, the finite element software was investigated to establish the model of the connecting rod. Then the model's stress distribution and sensitivity were analyzed. Based on the sensitivity analysis results, the appropriate design variables were selected to optimize the connecting rod aimed at least mass. The analysis results show that it can provide the reference for optimizing the structure of the connecting rod.
