中文摘要：采用Autoform中的增量计算法与双动拉延，对轿车引擎盖零件进行了冲压成形过程的仿真，预测了板料成形过程中减薄、拉裂和起皱等缺陷，同时分析了缺陷产生的原因。证明了仿真设计方法具有实用性；通过反复模拟，找出了合理的工艺参数。
英文摘要：The stamping form of hood outer panel was simulated by incremental numeration and double action drawing with Autoform software. The defects, such as thinning, fracture and wrinkling in the process of sheet metal forming, were predicted and the causes were analyzed. The reasonable process parameters were obtained by repeatedly simulating.
