The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。
