摘　　要：本文应用UG软件建立了发动机连杆的三维模型，并对连杆模型进行了结构强度分析和疲劳强度分析，得到了连杆在最大拉伸、最大压缩两种极限工况下的连杆的应力分布，确定了连杆工作的危险部位及易发生疲劳失效的部位，为连杆的设计开发提供参考。In this paper, UG is used to establish the three-dimensional model of the engine connecting rod. Under maximum tension and maximum compression of two kinds of limiting conditions, the stress distribution of the connecting rod is obtained by the structural strength analysis and fatigue strength analysis. The dangerous parts of the connecting rod and the location of the fatigue failure are determined. It provides reference for the design and development of connecting rod.
