Abstract：

For the defects that automotive engine hood inner panel tended to be crinkled and cracked during the forming process,using the plastic finite element method and sheet metal forming simulation software Dynaform，the forming parameters were optimized. The sharp corners of the product was optimized into round corners and the arrangement of drawbeads and height were also optimized to get a set of process parameters in order to avoid wrinkling and cracking, the qualified products were obtained,which provide a process reference for a similar drawing parts.
