摘　　要：利用CATIA软件建立驱动桥壳的三维模型,应用Hyperworks建立驱动桥壳虚拟试验台架仿真模型,运用Optistruct软件分析该驱动桥壳虚拟台架试验,得出桥壳的刚度、位移、应力以及桥壳本体的应力.对桥壳进行振动模态分析,验证桥壳应力集中位置分布的合理性.通过构造Kriging近似模型,对驱动桥壳进行轻量化优化设计,并对优化后的模型进行仿真验证.仿真结果表明,优化后驱动桥壳的质量有一定的减轻,其刚度、应力均满足台架试验要求,具有一定的实际应用价值.Using CATIA software to build a 3 D model of the drive axle housing,Hyperworks to establish simulation model for the virtual bench test of drive axle housing,and the Optistruct finite element method to analyze the drive axle housing under virtual bench test.The stiffness,displacement,stress of drive axle housing and stress of body part are obtained.The vibration mode analysis of the driving axle housing is analyzed to verify the rationality of the distribution of stress concentration.By constructing Kriging approximation model,light weight optimization design for drive axle housing is carried out,and the optimized model is simulated and verified,which proves that the mass of the drive axle housing is reduced.The stiffness and stress can meet the requirements of bench test and have certain practical application value.
