Abstract:

The numerical simulation on drawing process of automotive B-pillar was carried out on AutoForm software, and dangerous forming areas were discovered. The processing parameters, such as the layout of drawbeads, blank holding force and the shape of blank, were adjusted and optimized according to the simulation results. Results indicate that the quality defects can be forecast and removed, which improves the stability of forming process. The cost of design is decreased and the research cycle is shortened. It is proved that the drawing process and die design of B-pillar forming are feasible in actual production.
