摘　　要：铝合金是管件电磁成形中应用最广泛的材料之一。为了探究铝合金管件参数对自身成形性能的影响,利用Ansoft Maxwell电磁场模拟软件对3003系铝合金管件缩径变形进行仿真,分析了放电电压、铝合金管件长度和厚度对管件电流密度和电磁力的影响。研究表明,放电电压主要影响放电储能,当放电电压变大时,管件所受电磁力也增大;管件长度主要和线圈放电电流的幅值和频率有关,长度越大,电磁力也越大;管件厚度主要和趋肤深度有关,管件越薄,磁通量和能量的损失越多。Aluminum alloy is one of the most widely used materials for electromagnetic forming of tubes.In order to investigate the influence of aluminum alloy tube parameters on its forming performance,the necking deformation of 3003 aluminum alloy tubes is simulated by Ansoft Maxwell electromagnetic field simulation software.The effects of discharge voltage,aluminum alloy tube length and thickness on the magnetic stress of tubes are analyzed.The results show that the discharge voltage mainly affects the discharge energy storage.When the discharge voltage becomes larger,the magnetic pressure of the tube is also increased.The length of the tube is mainly related to the amplitude and frequency of the discharge current of the coil.The larger the length,the larger the magnetic pressure.The thickness of the tube is mainly related to the depth of the skin.The thinner the tube,the more the loss of magnetic flux and energy.
