基于1060铝合金筒形件旋压加工数值模拟

Numerical Simulation on Spinning Manufacturing for 1060 Aluminum Alloy Cylinder Part

采用有限元分析方法对1060铝合金筒形零件旋压加工进行数值模拟,分析旋压过程中零件应力、应变的变化情况,分析旋压进给率及旋轮工作角对旋压中应力、应变及旋压零件壁厚差的影响规律。结果表明:旋压过程中旋压力呈现3个阶段的变化,不同的进给率(f=2.5、3、4.5 mm/r)所产生的等效应力、应变变化趋势有所不同;对于同一进给率,在旋压过程中,等效应力、应变也在发生变化。并进一步分析了不同旋轮工作角(β=30°、45°、60°)所对应的应力应变及壁厚差的变化情况。

The numerical simulation on spinning manufacturing for 1060 aluminum alloy cylinder part was finished by using FEM.The influence rules of the feed rate and spinning wheel working angle on stress,strain and wall thickness difference were analyzed.The analysis results show that the spinning stress shows three periods changes during the spinning,different feed rate（ f = 2. 5、3、4. 5 mm/r） will lead to different equivalent stress and strain,even for the same feed rate,the equivalent stress and strain also change. The influences of spinning wheel working angle on stress,strain and wall thickness difference were also analyzed.
