Based on a static test studying the tension and compression on the connecting rod, the stress distribution of it was obtained. 3D modeling software was used to establish the connecting rod assembly 3D models, FEM software was used to do the load analysis, the result of FEM was very similar to the test. Then, the fatigue safety analysis of the connecting rod was carried out based on the results of com-puter simulations, the reliability of its structure was verified.
