Abstract
The forming process of automobile trunk side panel was investigated, using numerical simulation technology, to acquire the feasible process parameters and improve the formability of the product. With the technology, the manufacturability working procedures and drawing process parameters of the product were analyzed, calculated and simulated to achieve optimum formability characteristics. The method effectively lowers the probability of springback, wrinkling and thickness reduction, and shortens design cycle and cost. Based on the simulation results including forming limit diagram and thickness distribution diagram, the feasible process parameters are determined.
