摘　　要：运用ANSYS中的3D Maxwell与Transient structural进行耦合计算,对电磁胀形过程中铝合金管件受到的电磁力、等效应力以及径向变形量进行了有限元模拟,研究了成形螺线管线圈与铝合金管件在相对高度不同的情况下,随着螺线管线圈内径的改变,铝合金管件受到的电磁力的大小与产生变形量的变化情况。通过ANSYS软件的耦合分析发现:在电压为5500V螺线管线圈高度一定的情况下,随着螺线管线圈内径的缩小,铝合金管件的变形量显著降低。同时在螺线管线圈内径为R=9.9mm时,铝合金管件的变形量最为均匀且圆度可达0.1374mm,成形效果最佳。Using3 D Maxwell and Transient structural coupling calculation in ANSYS.The electromagnetic force,equivalent stress and radial deformation of aluminum alloy pipe during the electromagnetic bulging process are simulated by finite element method.The variation of the electromagnetic force and the deformation of the aluminum alloy tube with the change of the inner diameter of the solenoid coil is studied when the relative height of the forming solenoid coil is different from that of the aluminum alloy tube.Through the coupling analysis of ANSYS software,it is found that:When the voltage is 5500 V and the coil height of the solenoid is fixed,the deformation of aluminum alloy pipe fitting is significantly reduced with the reduction of the coil diameter of the solenoid.At the same time,when the inner diameter of solenoid coil is R=9.9 mm,the deformation of aluminum alloy pipe fitting is the most uniform and the roundness can reach 0.1374 mm and the forming effect is the best.
