摘要：电磁成形技术是一种典型的高速率电磁脉冲成形技术,可显著地提高材料的延展性,减小工件回弹和起皱,降低设备制造成本.在电磁成形技术发展过程中,电磁成形力场的有效加载和调控颇具挑战,早期的电磁成形方案基本实现工件排斥力成形效果,其电磁力分析中主要以排斥力占据主导,应用有较大的局限性,如今优势明显的组合式电磁成形技术开始进入大众视野.该文在简述电磁成形基本原理及电磁力调控方式的基础上,根据组合式方法应用的不同层面,将近年来涌现的研究成果划分为:驱动线圈组合式、电磁力组合式及工艺组合式三类电磁成形技术,针对每一类技术,分别阐述了其实施原理、技术方案及应用成效,并进一步归纳了不同技术的适用范围及研究重点.最后,在这些研究成果的基础上,对组合式电磁成形技术未来的发展方向进行了展望.
