Abstract：

For the automobile reinforcing plate, the joint tooling die was designed. Then, the finite element model of multi-step process was developed, and the numerical simulation of stamping process for the automobile reinforcing plate was carried out by the finite element software DYNAFORM. Therefore, the forming limit diagram of workpiece was obtained, and the corresponding experiment was carried out. The simulated results are in good agreement with the experimental results, which shows the validity of the present finite element model. Causes of the wrinkling and cracking during the forming process were analyzed, and the influences of blank holder force and position of drawbeads on forming quality were studied. Results show that by adjusting the blank-holder force and the drawbead setting, the wrinkling and cracking problem in the drawing process are solved, and the forming quality of product is improved effectively.
