摘　　要：针对汽车离合器盘毂齿形成形困难的特点,基于闭塞式锻造提出了完整的成形工艺方案。使用Deform-3D模拟软件分析了锻件的始锻温度、连皮厚度及位置对锻件成形时的最大等效应力、最大损伤因子、最大成形载荷的影响。通过数值模拟确定了最佳锻造温度、最佳连皮厚度及位置。模拟结果得到了实验验证。Aiming at the characteristics of forming difficulty for automobile clutch disc hub tooth shape, a full set of forming process was proposed based on closed-die forging. The influences of initial forging temperature, web thickness and position on the maximum equivalent stress, the maximum damage factor and forming force were analyzed by using the simulation software Deform-3D. Through numerical simulation, the reasonable forming temperature, web thickness and position were determined. The simulation results were verified by experiment.
