摘　　要：介绍了全工序仿真模拟分析方法,详尽阐述了双活动压料芯的模拟工具体设计,以及初始压料、下翻、上翻成形3个不同阶段的参数设置方法,准确模拟成形过程。针对压型过程中的孔位跑偏,进行逆向反算。并介绍了双活动压料芯压型模具的特殊结构及压料氮气弹簧的选用方法。This paper introduces the simulation analysis method of the whole process, and elaborates the concrete design of the simulation of the double active compacting core, as well as the parameter setting methods of the three different stages of initial compaction, downturning and upturning forming, so as to accurately simulate the forming process.Aiming at thehole position deviation in the pressing process, inverse calculation is carried out. In addition, the special structure of the double movable core pressing die and the selection method of nitrogen spring are introduced.
