摘　　要：文章采用有限元软件ANSYS 2D和ANSYS 3D模拟技术,研究电磁成形集磁器的工作原理。采用ANSYS2D模拟算法,研究集磁器的相对直径、厚度、中心圆孔半径等结构参数对被成形板料上电磁力分布和强度的影响,并提出提高集磁器效率和改善板料成形效果的途径;采用ANSYS 3D模拟算法,分析集磁器机理,并对ANSYS2D与ANSYS 3D的模拟分析结果进行比较,认为在保证准确度的前提下,采用ANSYS 2D模拟分析效率更高。The principle of field shaper in electromagnetic sheet metal forming was studied by 2D and 3D simulation of the FEA software ANSYS. The effects of relative diameter, thickness and diameter of the central hole of the field shaper on the distribution and intensity of the magnetic force upon the sheet metal were obtained by ANSYS 2D simulation. The ways to enhance the efficiency of the field shaper and improve the sheet forming results were proposed. ANSYS 3D simulation was taken to analyze the principle of field shaper. The comparison between the simulation results of ANSYS 2D and ANSYS 3D shows that with the premise of guaranteeing accuracy, the ANSYS 2D simulation is more efficient.
