Abstract

In this paper, with the ANSYS, stress distribution, safety factor and fatigue life cycle of connecting rod were analyzed by using 3D finite element method. The results show that the exposed destructive position is the transition location of small end and connecting rod shank at maximum compression condition. Maximum stress is 303 MPa. Safety factor is 1.24. At maximum stretch condition, the exposed destructive position is I-shaped cross-section at big end. Maximum stress is 118 MPa. Safety factor is 3.19. And structure of connecting rod is improved. Safety factor and fatigue life cycle of connecting rod increases.
