| 摘 要： | 基于AVL公司的Excite Power Unit软件进行连杆的多体动力学计算，得到连杆小头在发动机一个循环下的一维受力曲线，然后采用Abaqus软件进行连杆的有限元分析，得到连杆的三维应力分布，最后利用MSC.Fatigue软件导入多体动力学计算结果和有限元应力分布结果进行疲劳安全系数计算，得到疲劳安全系数的分布，从而为发动机连杆的优化设计建立基础。

| Abstract: | Based on the software of AVL Excite Power Unit, Muhi-body dynamic method is used to calculate the connecting rod small end force of one cycle. Then Abaqus is used to finite element analysis of connecting rod, where three-dimensional stress distribution can be got. Finally import the results of multi-body dynamic calculation and finite-element analysis to MSC.Fatigue software to calculate the fatigue safety factor of connecting-rod. These all may establish a basis to optimize the design of engine connecting-rod. |
