匀压力线圈能够产生近似均匀的磁场力，而不同结构电磁力均匀分布的差异较大。本文为研究匀压力线圈结构参数对板料电磁力均匀分布影响规律，基于ANSYS软件建立了3D电磁场有限元模型，分析了结构参数对磁压力均匀性分布的影响，给出了匀压力线圈提高电磁成形力分布均匀性的方法，对进一步提高电磁成形效果、扩大应用范围具有重要意义。 The approximate uniform magnetic field force can be generated by uniform press coil, and the differences of uniform distribution of magnetic field force by different coil structures are significant. In order to study the effect law of coil structure parameters to uniform distribution of magnetic force in electromagnetic sheet forming, the 3D finite element models for electromagnetic field analysis were established by software ANSYS. The structure parameters on the distribution uniformity of the magnetic pressure were analyzed. The method of improving the electromagnetic forming force distribution uniformity of uniform press coil was proposed, which will improve the effect of electromagnetic forming and expand the scope of the application.
