Fatigue Analysis of Engine Connecting Rod Based on Workbench

Abstract

The connecting rods are subjected to complex loads during engine operation. The load and boundary conditions of the connecting rod are obtained by kinematics and kinetic analysis, and the finite element model is established. In this paper, the connecting rod is analyzed statistically and the weak position of the connecting rod is determined. Then, under constant amplitude loading and cyclic loading of two different loads, the fatigue life and safety factors of the connecting rod are analyzed, to predict the fatigue life of the connecting rod and provide effective guidance for the future design of the connecting rod.
