Abstract：

In view of defects in the forming process of automobile side wall plate, the stamping process simulation technology was studied. For the automobile side wall plate, the stamping process and results were analyzed, and the non-uniform deformation and partial fracture phenomenon were found. Aiming at solving the forming defects, the process parameters and conditions were optimized by adding fourteen drawbeads, adjusting the drawbead resistance reasonably, increasing the blank-holder force to 100 kN and improving the lubrication conditions. Therefore, the improved model of stamping was established, and the simulation analysis was carried out again. Thus, the fracture and wrinkle defects are eliminated, and the variation in thickness is uniform. Furthermore, the feasibility of the stamping process scheme is verified by experiment. The research result shows that the proposed simulation technology of stamping process is highly practical.
