摘要

运用DEFORM-3D有限元软件对铝合金筒形件旋压成形过程进行了数值模拟。通过在不同参数下的模拟

得出了一组较优的工艺参数

即:旋压温度为20℃

主轴转速为400r/min

壁厚减薄率为50%

旋轮进给率为0.75mm/r。同时分析了最优化模拟条件下工件变形区的应力、应变状态

即在毛坯与旋轮的接触区

等效应力和等效应变达到最大值。径向方向受到的力是旋压力的主要表现形式。

Abstract

The spinning forming process of aluminum alloy cylindrical workpieces was simulated numerically by the Deform-3D software. Optimized processing parameters were presented including spinning temperature of 20 ℃

main axle rotating velocity of 400 r/min and 50% reduction of wall-thickness as well as feeding rate of 0.75 mm/r through simulation with varied parameters. Meanwhile

stress and strain distribution in workpieces deformed zone were simulated with the optimized parameters. The results show that maximum value of equivalent stress and equivalent strain can be observed in the contacted zone of blank with spinning wheel. Spinning force is mainly exhibited as exerted force at axial direction.
