Abstract: The flanging process was reappeared by using finite element method. By comparing the practical cases, the feasibility of finite element analysis and the effectiveness of measures to solve the flanging cracking were verified. The finite element analysis could effectively guide the design of process parameters, shorten the rectification period of the later matching size of the body.
