摘要： 随着我国高端制造业的发展，航空航天等众多工业领域对薄壁构件的需求急剧增加。传统的电磁成形凭借其高速率成形特性，已成功应用于某些关键轻质材料薄壁构件的生产制造中，但受到成形线圈和放电设备的限制，难以加工大尺寸、结构复杂的零件。近十几年来，渐进式电磁成形技术逐渐被开发，并应用于大型薄壁构件的加工中，在此期间大量研究成果也随之涌现。在简述电磁成形技术原理及特点的基础上，按照工艺形式将现有渐进式电磁成形技术划分为两大类：渐进式电磁复合成形和渐进式电磁直接成形；针对每类工艺从基本原理、技术方案以及应用成果等方面进行了研究现状阐述；分析了渐进式电磁成形技术目前存在的主要问题，并对渐进式电磁成形技术的未来发展前景和研究方向进行了展望。

Abstract: With the development of Chinas high-end manufacturing industries, the demands for thin-walled components in many industrial fields such as aerospace were increased dramatically. The high-speed forming characteristics, traditional EMF was successfully applied to the production of thin-walled components of some key lightweight materials. However, due to the limitations of forming coil and discharge equipment, it was difficult to process large-scale and complex structure parts. In the past decade, incremental EMF technology was developed and gradually applied to the large thin-wall components processing, where a large number of research results were emerged. On the basis of briefly describing the principle and characteristics of EMF technology, the existing incremental EMF technology was divided into two categories according to the processing form: incremental electromagnetic composite forming and incremental electromagnetic direct forming. The research status of each processes was expounded from the aspects of basic principle, technical scheme and application results. Thus the main problems existing in the incremental EMF technology were analyzed, then the future development prospects and research direction of the incremental EMF technology were prospected.

Key words: thin-walled component, incremental, electromagnetic forming(EMF), incremental electromagnetic composite forming, incremental electromagnetic direct forming
