Abstract：

The structure and shape of car support base parts are extremely complex and require high forming precision, so it is difficult to accurately determine blank shape and size as well as whether there will be crack at once forming by traditional blank expansion method and forming limit method. Therefore, the stamping process of car support base was numerical simulated by software Dynaform so as to determine blank shape and size as well as whether there would be crack. Then, stamping process plan, nesting drawing and die structure were optimized. At last, the stamping process tests of the support base were done. The results show that qualities of support base obtained by stamping meet the requirements, and correctness of simulation results are verified.
