Fatigue Analysis of Diesel Engine Connecting Rod Based on Finite Element Method

Xin Fan, Mao Hui Pan, Cheng Song Zhang

Abstract

Connecting rod fatigue in a certain type of diesel engine is analyzed by using finite element analysis method and the FEM software ANSYS. According the actual working conditions, the three-dimensional model with multi-body contact is established to simulate the contact between the connecting rod parts; By using APDL language programming, the work load on the connecting rod, calculated according all the link work loads, is applied to the connecting rod bearing and bushing through the oil film pressure distribution. By finite element method structural strength of the connecting rod was calculated, that can effectively guide the connecting rod design, which has been proved by practice.
