摘　　要：应用金属成形有限元数值模拟技术 ,以ObjectARX为二次开发工具 ,采用面向对象技术的模块化设计思想 ,建立了大口径、厚壁不锈钢球壳类零件拉伸模CAD系统 ,有效地提高了球壳类零件拉伸模的设计效率和设计水平。With the object-oriented modular design theory and the FEM simulation technology for metal forming,and with ObjectARX as the tool for secondary development,a CAD system for the drawing dies for large-caliber and thick-wall hemispherical-shell stainless-steel parts was built up,which has effectively improved the efficiency and level for designing the drawing dies for hemispherical-shell parts.

关 键 词：厚壁球壳 成形 有限元模拟 模具CAD OBJECTARX
