目前金属板料成形工艺制定和模具设计仍然采用传统的单纯依靠工艺人员的经验和试模生产验证的方法进行，难以掌握成形过程材料的流动情况，以及进行工艺参数的优化．针对设计生产中这一普遍状况，介绍金属板料成形过程计算机仿真技术，探讨了在生产实际中应用ＣＡＥ技术的技术路线．通过比较单工步成形和多工步成形分析的技术特点，介绍了多工步成形过程的计算机仿真中的信息传递，并给出汽车轮辐多工步成形过程仿真的成功案例．
At present, the process of sheet metal forming process and mold design still rely on the traditional experience of relying solely on the process staff and test-mold production verification method, it is difficult to grasp the flow of material during the forming process, as well as the optimization of process parameters. Aiming at this common situation in design and production, this paper introduces the computer simulation technology of sheet metal forming process and discusses the technical route of applying CAE technology in production practice. By comparing the technical characteristics of single-step forming and multi-step forming analysis, the information transfer in computer simulation of multi-step forming is introduced and the successful case of multi-step forming of wheel spoke is given.
