| 摘 要： | 利用有限元软件Deform-2D，对奥氏体不锈钢变薄拉深过程进行热力耦合的数值模拟，研究了凸、凹模与坯料间摩擦和变形速度对变薄拉深过程的成形载荷和坯料损伤的影响。模拟结果显示：当凹模与坯料之间的摩擦增大，成形载荷和坯料损伤明显增大；当变形速度增大，坯料损伤增大而成形载荷减小。上述结论为奥氏体不锈钢变薄拉深工艺优化设计提供了可靠的理论依据。

| Abstract: | The thermo-mechanical coupling numerical simulation of the ironing process of austenitic stainless steel was conducted by Finite Element software Deform-2D, The influences of interface friction and deformation speed on the forming load and billet damage were studied in this paper. The simulation results showed that the load and damage increased obviously with the increase of the friction between the billet and the die; the billet damage increased and the forming load decreased with the increase of deformation speed, These conclusions provide a reliable theoretical basis for the optimization of the ironing process of austenitic stainless steel. |
