对ＸＮ－１０４０轻型汽车后桥壳体进行三维有限元应力计算，并分析计算结果，得到该型后桥壳体的应力大小，位移大小，应力分布状况，并通过Ａｎｔｏ－ＣＡＤ１１．０构造变形前后的三维线框模型．从而直观的分析后桥壳体的变形．
After three-dimensional finite element stress calculation of XN-1040 light vehicle rear axle shell, the stress magnitude, displacement magnitude and stress distribution of the type rear axle shell were obtained and analyzed by Anto-CAD11.0 before and after deformation 3D wireframe model. Thus intuitive analysis of the deformation of the rear axle housing.
