摘要: Production of high strength steel bumper can greatly enhance the occupant safety. However, it is very hard to form high strength steel plate. There is rare domestic successful reference. The hot stamping technology aboard increases costs significantly, and the efficiency is low. Therefore, the only solution is combining advanced numerical simulation technology with current adjusting stamping process. The cold-forming process of a sedan's high strength steel bumper is simulated by FEM software Dynaform and the results show that springback and crack are the main defects. A law is summed up by researching the influence of different shapes of addendums on part forming and springback. Finally, the optimized shape of addendum is obtained by adjusting the addendum and adding convex roofs. It provides references for manufacturing similar high strength steel parts.
