As an important component of the engine power transmission system, Connecting-rod is the key component in the engine design and development. In order to the fatigue analysis of the compound movement parts of the Petrol engine, Three-dimensional nonlinear contact finite element method (CFEM) of the connecting-rod of 474Q engine was set up, and tress and strain fields were computed by using Nastran finite element soft. Based on this, the fatigue strength of the connecting-rod were analyzed according to the Good-man law and the stress life law, After experimental verification, the analysis of the connecting-rod is correct, The results show that connecting-rod of 474Q engine can achieve the requirements of Fatigue strength under current lighter design, so it provides not only the theoretical foundation to improve design and engine performance development, also optimums design method for three-dimensional component with component interactions.
