Abstract
Numerical simulation is of great importance in sheet metal multistage deep drawing forming, optimizing mould design and improving mould research and development capability. Now researchers have proposed the numerical simulation general steps of multistage deep drawing, but there are still many problems to be resolved. This paper, comprehensively considering the two important factors of influencing the accuracy of the numerical simulation, introduces the numerical simulation simplified steps of two pass stamping forming. Results show that this new method is effective and successful in simulating two pass deep drawing forming, and the simulation results are more reasonable.
