摘　　要： 对高性能电池壳用电沉积镍涂层钢板的拉延成形过程进行了研究 .提出了涂层薄板拉延成型的力学模型 ,并运用L啨ｖｙ Mises增量理论、平衡微分方程和修正的Tresca屈服条件得到了凸缘变形区和凹模圆角区的应力 .将计算所得的冲头压力和有限元模拟的结果进行了比较 ,并进行了试验 .结果表明这种分析方法是可以接受的 .分析结果对高性能电池壳的拉延生产以及这种涂层的制备与工艺具有参考价值 . The drawing process of a good quality battery shell is investigated. A mechanical model is proposed to study the drawing process of the steel sheet with electrodeposited nickel coating used for the battery. The coating and sheet in the drawing process are studied by using Lévy-Mises incremental theory, differential equation of equilibrium and modified Tresca yield criterion. The stresses in electrodeposited nickel coating and steel substrate are calculated especially in the regions of the flange and the die profile. Some results are compared with the numerical simulation of finite element method and with workshop test result. The results are helpful for the design and fabrication of the electrodeposited nickel coating, and useful for the determination of parameters in the battery drawing processes.
