某微车驱动桥壳的强度研究

A minicar drive axle shell strength research

针对目前驱动桥壳有限元模型中没有考虑悬架运动,造成约束条件和加载位置难以确定,从而影响计算结果的问题,文章以某微车后驱车桥壳为研究对象,提出了在悬架系统中进行桥壳的有限元分析,在有限元模型中引进了板簧、衬套、减振器和吊耳,统一了边界条件,克服了有限元模型中约束条件和加载位置难以确定的问题,研究结果表明,该方法更能准确的反映驱动桥壳的应力水平,为驱动桥壳的强度分析提供指导作用。

Aimed drive axle shell finite element model does not consider suspension movement at the present,cause the constraints and loading position is difficult to determine,which affects the calculation results,this paper takes a minicar drive axle housing as the research object,the suspension system are proposed during drive axle finite element analysis,the leaf spring,bushing,shock absorber and lug is introduced in the finite element model,unified the boundary conditions,overcome the constraint and loading position problem in the finite element model is difficult to determine,the research results show that this method can more accurately reflect the drive axle shell stress levels,provide guidance for the analysis of the strength of the drive axle housing.
