| 摘 要： | 运用动显式有限元软件LS-DYNA对某1t轻型车后桥壳液压胀形过程进行了仿真，针对后桥壳两次液压胀形时的胀形比、载荷匹配及摩擦力等因素对液压成型的影响进行了分析。通过厚度分布、轴向收缩量、内压力及轴向力的试验与仿真对比，验证了仿真结果的正确性，同时讨论了仿真与试验结果之间产生误差的原因。

| Abstract: | In this paper,the FEM sofiware,LS-DYNA,is used in the analysis of the process of the hydraulicbulge of real axle housing of lton vehicle.Some factors such as bulge ratio,loading matching and friction coefficient,which influence the hydraulic-bulge of real axle housing,are mainly analyzed.Through the contrast between experiment and simulation,including the display of thickness,the axial shrinkage,inner force and axial force,the simulation results are good agreement with experimental data,at the same time the causes of resulting in errors between the theoretical and experimental results are discussed. |
