摘　　要：为介绍驱动桥壳试验台架虚拟模拟的理论基础与一般方法,在ADAMS中建立了桥壳的柔性体虚拟样机试验台,仿真模拟试验的加载及约束等条件,进行幅值为2.5倍满载的不对称循环载荷在不同频率下的响应分析,得到桥壳的模态位移及相应工况下的桥壳应力最大点。比较不同频率下的桥壳最大应力值及其对应位置,可以快速找出桥壳薄弱区域,减少并缩短工程试验的成本和周期。This paper introduces the theoretical foundation of virtual simulation and the general method for drive axle ease test stand. The virtual prototype test stand of drive axle ease was established with ADAMS to simulate testing load and cnnstraint. At the same time the response was analyzed in the cases of asymmetry 2.5 full-loaded and at the different frequency to find the point where the stress of the drive axle has maximum value. The maximum stress and its corresponding position were compared at the different frequency in order to discover the weak area where the drive axle case has, reduce the cost of test and shorten the test cycle.
