摘　　要：基于开发的多工艺方案管理系统,构建了拉深筋多工艺方案优化方法。先通过多工艺方案管理系统,将自动生成的工艺方案分配到计算机集群中的单个计算机上,多台计算机并行求解,每台计算机采用增量法求解器单独计算一个工艺方案,再根据计算结果进行拉深筋工艺参数优化,并根据优化的工艺方案,反求拉深筋几何参数,用于工艺设计。最后以实例验证了方案的可行性。An optimization method of drawbead design was proposed based on the developed multi-process management system. First, the serialized process plan was generated automatically with the management system and each plan was analyzed in parallel in the computer cluster with the incremental method. Then, the drawbead process parameters were optimized according to the calculated results, and the drawbead geometry parameters could be calculated with the opti- mized process parameters reversely. Finally, an example was tested to verify the feasibility of the method.
