| 摘 要： | 针对某越野车在改型过程中后桥壳在台架疲劳试验时出现局部开裂的情况,应用ADAMS/Car建立了整车动力学模型,进行动力学仿真,得出危险工况冲击载荷下桥壳的受力情况.采用ANSYS Workbench对桥壳进行了疲劳寿命计算,结果与试验吻合.分析其存在的不足,并提出了改进方案.对改进后的桥壳再次进行疲劳计算,满足设计要求,试制后进行台架试验,寿命达到国家标准要求.

| Abstract: | In view of crack occurrence of rear axle housing in fatigue test during the course of a SUV modification,a complete vehicle dynamics model is built using ADAMS/Car and a dynamics simulation is conducted with the forces exerted on axle housing in critical impact loading conditions obtained.The fatigue life of axle housing is calculated by using ANSYS Workbench,which well agrees with test results.The causes of defects are analyzed and some improvement schemes are proposed.The fatigue life of modified housing ... |
