摘　　要：本文以车身一内支撑板作为对象，通过数值模拟技术对其冲压成形过程进行了有限元仿真，在对工件成形过程中出现的起皱、拉裂和回弹问题进行分析后，对冲压工艺进行了调整修改，得出了合理的冲压成形和冲模结构方案。结合有限元仿真技术的冲压工艺设计和冲模结构设计，相对传统的“试制-调整-试制”经验方法来说，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生产的周期。Taking an automotive panel as an example in this paper, we have made a simulation to sheet stamping process using finite element method, analyzed the defects as wrinkle, crack and springback that occur in stamping. After adjusting the stamping process parameters, we get a feasible stamping process scheme and die structure. In fact, compared with traditional method of ＂trial-error-trial＂ , the design method that integrates with finite element technical would not only reduce the technical requirement to the worker, but also enhance the production efficiency, reduce the production cycle of die design.
