摘　　要：汽车覆盖件的生产是一个复杂的系统性工程,其复杂的生产工序及高昂的生产成本必然要求严格的风险控制。在复杂的生产工序中,冲压成形是其中最关键的一环,因为它不仅能决定成形的质量,还会影响后续工序的设计与生产。因此,保证成形工艺科学可行就显得尤为重要。而传统的解析法和实验法存在很大的不确定性,要想将这种不确定的风险控制在可接受范围内,必须在实际生产之前确保成形工艺切实可行。利用PAM-STAMP软件针对成形工艺进行有限元分析,能在设计初期对成形工艺进行验证,找出潜在的成形缺陷类型及具体位置,进而分析原因,优化方案,消除风险。以汽车前围板加强梁为例,设计成形工艺,并进行有限元模拟分析,进而优化工艺,并验证其可行性。The production of automobile panels is a complex systematic project. The complicated production processes and high production costs inevitably require strict risk control. In the complex production process,stamping is most critical, since it not only determines the forming quality, but also affects the design and production of subsequent processes. Therefore, it is particularly important to ensure that the forming process is scientifically feasible. However, the traditional analysis methods and experimental methods have great uncertainty. In order to control this uncertain risk within an acceptable range, it is necessary to ensure that the forming process is feasible before actual production. The PAM-STAMP software has been used for finite element analysis of the forming process. The forming process can be validated in the early stages of the design to identify potential defect types and locations. Then the reason has been analyzed and the proposal has been optimized, which eliminates the risks. Taking the reinforcing beam of automobile front panel as an example, the forming process has been designed, and finite element simulation analysis has been performed to optimize the process and verify its feasibility.
