In order to improve the forming quality of the automobile fender,this paper proposes to optimize the forming parameters of fender by using multiple regression method based on the simulation of fender stamping process and the analysis of its stamping parameters,so as to determine the best combination of stamping process parameters.Through the simulation and physical analysis,the results show that the proposed method can guide the fender generation process,and the overall modeling allowance of the fender meets the safety requirements.
