发动机粉锻连杆在工作温度下的有限元分析

摘要

The impact of working temperature on the strength and fatigue of the connecting rod produced by iron powder forging by u-sing Abaqus and nSoft is dicussed. ln accordance with the actual working conditions, the thermosetting coupling model of the rod as-sembly is established in Abaqus to calculate the structural strength of the rod. The results of the calculation are put into nSoft, and the fatigue safety factors in room temperature and working temperature are calculated.%利用Abaqus和nSoft探讨了工作温升对铁基粉锻连杆的结构强度和疲劳性能的影响。根据连杆的实际工作状况，在Abaqus中建立连杆组的热固耦合模型，进行结构强度的计算。将Abaqus的计算结果导入疲劳分析软件nSoft中，计算了连杆在室温和工作温度下的疲劳安全系数。
