| The aim of this study was to investigate the stamping process of anticollision beam plate for automobile. The design of the technological supplementing surface， BHF and the layout of drawbead were always the important aspects during the stamping process design of automobile panel. Taking anticollision beam plate as an example， based on surface modeling and finite element simulation software， its stamping process was designed， simulated and optimized. After the optimization of process parameters and improvement of the part′s structure， a better result was obtained，and it could be used for the actual process design and tryout production. This paper proposed a new idea， in which using the multi-step stamping process and reasonably adjusting the part′ s structure to reduce the manufacturing difficulty of drawing process and finally to improve the part′s quality. |
