摘　　要：The paper starts with a brief overview to the necessity of sheet metal forming simulation and the complexity of automobile panel forming, then leads to finite element analysis (FEA) which is a powerful simulation tool for analyzing complex three-dimensional sheet metal forming problems. The theory and features of the dynamic explicit finite element methods are introduced and the available various commercial finite element method codes used for sheet metal forming simulation in the world are discussed,and the civil and international status quo of automobile panel simulation as well. The front door outer panel of one certain new automobile is regarded as one example that the dynamic explicit FEM code Dynaform is used for the simulation of the front door outer panel forming process. Process defects such as ruptures are predicted. The improving methods can be given according to the simulation results. Foreground of sheet metal forming simulation is outlined.基于板料成形模拟的必要性和汽车覆盖件成形的复杂性 ,提出有限元分析是模拟复杂三维板料成形问题的有力工具 .介绍了动态显式有限元法的原理和特点 ,讨论了国际现有的各种商用软件 ,论述了汽车覆盖件模拟的国内外应用现状 .以某新型汽车前门外板为例 ,运用显示有限元分析软件Dynaform对前门外板冲压过程进行了计算机模拟分析 ,预测冲压过程中可能出现的各种工艺缺陷 ,例如坯料的破裂 ,并以模拟结果为依据提出改进方法 .
