曲面零件的冲压成形属于复合成形,其成形过程中出现的各种缺陷仍是研究的热点。目前研究板料成形的主流方法是数值模拟法和实验验证法,但理论分析仍是进行数值模拟和实验验证的基础。从力学方面解析了曲面零件拉深过程中的应力状态,指出了成形过程中的主要影响参数及其影响规律,为进一步的数值模拟和实验验证奠定了理论基础。 Stamping parts of the surface are composite forming, the forming process of the various defects is still a research hot spot. At present, the mainstream methods of sheet metal forming are numerical simulation and experimental verification, but the theoretical analysis is still the basis of numerical simulation and experimental verification. From the mechanics aspect, the stress state during the drawing process of the surface part is analyzed. The main influencing parameters and their influence laws during the forming process are pointed out, which lays a theoretical foundation for further numerical simulation and experimental verification.
