Abstract：

For the fracture of front clapboard stamping parts of an automobile during drawing forming, the drawbead resistance coefficients were optimized by central composite test method. The finite element model of the products was built by AutoForm software, a single factor simulation was conducted and the approximate range of each section of drawbead was determined. The experiments of the factors were designed by central composite tests, and all the experiment groups were simulated by the finite element software. The maximum thinning ratio and the maximum thickening ratio were taken as the optimization objective. The optimal combinations of the drawbead resistance coefficients were A=0.25, B=0.45, C=0.30 and D=0.30 respectively by the Design-Expert software. The optimal parameter combinations were verified by the experiment, and the experimental results show that the proposed method can effectively improve the forming quality of drawing parts.
