Abstract：

The stamping process design , forming springback analysis, springback control method and effect of DP780 longeron after-reinforcing plate of Peugeot car were presented. Through the analysis of the data before and after springback by digital simulation Dynaform, and according to the performance and geometry of the part, the measure of adding strengthening rib and groove can be applied, which could reduce the springback by 45% and achieve the longitudinal design requirements and assembly needs.
