微型车驱动桥壳不同工况下强度有限元分析

Strength Finite Element Analysis of Mini Car Drive Axle Housing under Different Working Conditions

针对微型车驱动桥壳强度设计的需要,进行了不同工况条件下强度有限元分析方法的研究。在SolidWorks建立驱动桥壳实体模型的基础上,导入Ansys Workbench 17.0中划分有限元网格和添加约束条件并施加载荷,对四种工况下受力驱动桥壳体应力和应变分布情况进行了有限元仿真分析,结果表明此型号驱动桥壳满足强度要求和变形量要求。为驱动桥的改型设计和后续优化设计提供了分析对照依据。

In this paper, aiming at the strength design requirements of mini car drive axle housing, studies on the strength fi- nite element analysis under different working conditions are conducted. After building solid model of the drive axle housing in the SolidWorks, the solid model of drive axle housing is imported to the Ansys Workbench 17.0 to generate finite element grid. Then by adding constraints and loading forces, the finite element simulative analysis on the stress and strain distribution of the drive axle housing based on four types of working conditions of vehicle are conducted. The result of analysis indicated that this type of drive axle housing could meet the strength requirements and deformation requirements. This conclution can provide analytical basis for the model change and the later optimal design of the drive axle in the future.
