Abstract：

The forming process for an automotive underbody cross member was simulated by the FE method.The drawbead was adopted to control the flow of the material.The parameters for drawbead had some effects on the forming process.Firstly,the effect rules of the parameters for drawbead on the simulation results could be obtained by carrying out FE simulation for parts with simple shapes.Then the cross member model was modified for several times according to these rules.By comparing the simulation results obtained by adopting the equivalent drawbead and the real drawbead,the real drawbead model should be used in simulating the stamping process of complex parts.
