By using non-linear finite element theory, a non-linear finite element model for hydroforming for rearaxlehousing is established.
利用非线性有限元理论方法，建立了后桥壳液压胀形有限元模型。

According to the characteristic of hydroforming for rearaxlehousing, rigid-plastic material model is elected as tube blank material model process simulation analysis.
根据后桥壳液压胀形的特点，选择刚塑性材料模型进行模拟分析。
