The Engine Connecting Rod Strength Evaluation and Fatigue Analysis

Abstract:

In this paper, all parts of the gasoline engine connecting rod were assembled and the stress analysis was executed in two working cases of the maximum explosion pressure and the maximum inertia force based on ABAQUS. According to the simulation results from two above working cases, the engine connecting rod strength was evaluated comprehensively, which could satisfy the rod design strength requirement. And meanwhile the high cycle fatigue analysis of the connecting rod was also completed in fatigue safe module. The fatigue simulation result showed that the safety factor was greater than the specified value and the connecting rod was reliable.
