| 摘 要： | 针对某汽车驱动桥差速器壳体断裂情况,首先利用材料试验检验分析了该驱动桥差速器壳体所采用球墨铸铁材料的金相组织和铸造等级,然后根据试验标准,采用有限元分析方法建立了该差速器壳体的有限元模型,利用有限元分析软件ABAQUS进行差速器壳体的静强度分析,得到了该差速器壳的应力分布情况和应力集中部位.通过与样件失效部位对比分析,确定了该差速器壳体断裂失效的原因,为改进设计提供了理论依据.

| Abstract: | In view of the breaking of differential housing of driving axle, the metallographic structure component and the foundry grade of the ductile cast iron adopted in differential housing of the driving axle are analyzed by the material test. According to the standard of 'Q/T 543-1999 Drive Axle Bench Test Evaluation Criteria', a finite element model is then built with finite-element analysis method, and the static strength analysis is made by ABAQUS, a software of finite-element analysis and obtain some informa... |
