摘　　要：以车身支撑板为对象,通过数值模拟技术对其冲压成形过程进行了有限元仿真,对工件成形过程中出现的起皱、拉裂和回弹问题进行分析,对冲压工艺进行了调整修改,得出了合理的成形工艺和冲模结构。此方法与传统的试制—调整—试制的经验方法相比,不但可以降低对技术工人的要求,而且可以提高设计生产的效率,有效缩短模具设计和制造的周期。Finite element simulation was made on the stamping process of a vehicle body support plate and analysis was carried out on the defects occurred such as wrinkling, tension crack and springback. A feasible process and a die structure were obtained which can decrease the requirement for technical workers and increase the design and production efficiency.
