Study on Forming Process of Automobile Anti-collision Beam Based on Dynaform

The mechanism of the automobile anti-collision beam forming was studied, and the forming process was analyzed by using Dynaform and the finite element simulation in view of the defects such as wrinkling and cracking. The blank holder force and drawbead layout for the quality of the parts were further researched in drawing process. The results show that the simulation analysis provides the basis for the improvement of the mold structures and the optimization of the forming process parameter, and it can greatly shorten the die manufacturing cycles, reduce the production costs and improve the production efficiency.
