摘　　要：利用板料成形有限元软件对某轿车车门内板的一次拉深过程进行了数值模拟,分析了其成形过程中的危险区域,并对拉深过程中的缺陷产生原因进行了分析,通过调整工艺参数,得到比较理想的结果,可为该零件实际生产提供参考。The one-off deep drawing process for door inner panel of certain car type was numerically modeled and simulated by utilizing commercial code of sheet metal forming. With the appropriate material, the critical forming zones were indicated, and factors which cause defects in the course of drawing were analyzed. The reasonable result was obtained by modulating rational technology parameters, which provides significant reference for practical manufacturing of this part.
