| Abstract: | Based on finite element, the drawing formation process of an auto structure part was analyzed.The process parameters influencing the forming quality were optimized.The emphasis of the optimization was the blank shape and part surface.The blank shape and surface of part were determined after analyzing the FLD diagram and the forming result.Finally by comparing the simulation results after optimization with the experiment results, the validity of numerical simulation was validated. |
