摘要
为满足某低速电动汽车驱动桥桥壳刚度、强度设计要求,根据该桥壳实际受力特征,对其在不同工况条件下的刚度、强度进行有限元分析。在CATIA中建立驱动桥桥壳各零部件的实体模型并进行装配;将装配体模型导入ANSYS Workbench中,建立各部件间的连接关系、划分有限元网格、添加约束条件并施加载荷;对4种工况下驱动桥桥壳应力和应变分布情况进行了有限元仿真。仿真结果表明,该驱动桥桥壳满足刚度、强度及变形量要求,为驱动桥后续改进优化提供了对照标准。
In order to meet the stiffness and strength design requirements of low-speed drive axle housing, the finite element analysis on stiffness and strength under different working conditions is carried out according to the actual stress characteristics of the axle housing. The solid model of drive axle housing parts was established and assembled in CATIA. The assembly model was imported into the ANSYS Workbench where the connection relationship between the parts was established, the finite element mesh was divided, constraints were added and loads were applied. The finite element simulation analysis of the stress and strain distribution of the axle housing of the drive axle under four working conditions was conducted. Simulation results show that the axle housing meets the requirements of stiffness, strength and deformation, which provides a reference standard for the subsequent improvement and optimization of the axle.
