铝合金管材空拉减径时受力情况和壁厚变化分析

摘要

通过分析铝合金管材空拉减径时,不同直径、壁厚、减径量、直径与壁厚比对管材内部金属受力的影响,分析得出空拉减径后管材壁厚的变化规律.%The paper analyzed the effects of different diameters, wall thickness, tube reducing and ratio of diameter to wall thickness on the forces of internal surface of aluminum alloy tube in sinking;it concluded the change law of wall thickness after sinking.
