摘要：

Taking the front floor of a car as an example, the finite element software Autoform was used for numerical simulation analysis of forming process. The defects such as splitting, wrinkling, and failure during the forming process of the sheet metal were predicted through simulation analysis. By adjusting the size of the blank holder force, the drawbead parameters, the offset between the punch and the die, and the friction coefficient, the simulation results were optimized to obtain a set of the most suitable parameters for actual production process. After setting the variable strength double drawbeads, the optimum conditions for the process parameters are: blank holder force is 650 kN, forming force is 5200 kN, the offset between punch and die is 0.8 mm and the friction coefficient is 0.15. Based on the simulation results, a forming experiment was carried out and a qualified forming part was obtained, which effectively shortened the development cycle of the die and reduced the design cost. © 2019, Jilin University Press.
