摘　　要：采用有限元法对某驱动桥壳进行瞬态动力学分析,得出了驱动桥壳在函数载荷作用下的位移与动应力-时间响应值;根据驱动桥壳的动应力分析结果,利用有限元法对驱动桥壳进行疲劳寿命分析,得到了桥壳整体的疲劳寿命分布,其危险部位主要分布于板簧座区域,与台架疲劳试验结果基本一致。The transient dynamics analysis of drive axle housing is obtained by using the finite element method, by which the time response values of displacement and dynamic stress of drive axle housing applied with the function loading are obtained. The fatigue life of drive axle housing is obtained by using the finite element method according to the dynamic stress analysis results of drive axle housing. The most dangerous position dis- tributed aroud the spring seat,which is consistent to bench fatigue test basically.
