Abstract：

In order to improve the forming quality of rear part of automobile front floor, a finite element model of the drawing process was established, and the drawing process was simulated by finite element software AutoForm. Then, the drawing technological parameters were optimized by combining the orthogonal experiment design with numerical simulation. During the analysis of simulation, the maximum thinning rate was used to reflect cracking index, and the maximum wrinkling criterion was used to reflect the wrinkling index. Finally, the optimal combination of process parameters was obtained by the multi-objective optimization method, and the optimal parameters were verified by experiment. The experimental results show that the proposed method can effectively control the cracking and wrinkle of automobile front floor rear part.
