摘　　要：利用CATIA软件建立驱动桥壳的三维模型,选取桥壳的最大垂向力、最大牵引力、最大制动力、最大侧向力和最大静应力典型工况,并施加相应的约束和边界条件,在Hyperworks中对桥壳进行有限元结构分析。分析结果表明,桥壳的强度及刚度性能满足要求。在最大静应力工况下,运用Optistruct优化模块对驱动桥壳的盘面和板簧座进行结构优化,优化后桥壳的应力集中位置得到转移和分散,桥壳应力分布较均匀,实现了桥壳的轻量化。A three-dimensional CATIA model of the drive axle is established. In the typical working conditions of the maximum vertical axle, tractive force, braking force, lateral force and the maximum stress, the structure of the axle shell is analyzed by the finite element in the Hyperworks under the corresponding constraint and boundary conditions. The analytical results show that the strength and stiffness of the axle shell can meet the requirements of performance with a surplus. In the maximum static stress condition, the Optistruct optimization module is used to optimize the shape of the drive axle disk and spring seat. The stress concentration position of the optimized axle housing is in the state of transfer and dispersion and its stress distribution is more uniform, implementing the lightweight of the axle shell.
