Connecting Rod Design Based on Finite Element Analysis

In this paper the finite element analysis of connecting rod is given first,by which the stress concentrate point and the worst deformation are determened.Then the piston's sensitivity analysis subject to the stress concentrate point and other relative parameters and dimensions are carried out and the parameters which influence stress mostly are found.(Finally),aimed at least mass,the connecting rod optimieation based on the optimized design technology and finite element(analysis) is attained.
