摘要：

电磁成形能有效地提高轻质合金的成形性能,线圈结构是影响成形质量的关键因素之一。本文介绍了电磁成形的基本原理,分析了线圈结构与电磁力分布的关系,指出线圈结构能够控制变形力的分布,要根据工件变形部位的需要来确定电磁力的分布并设计与之相适应的线圈。按照结构形式将线圈进行了分类和详细介绍,并举例说明了各类线圈的典型应用。

Electromagnetic forming can effectively improve the formability of light-alloy,the configuration of the coil is one of the most important factors that influence forming quality.The principle of electromagnetic forming was introduced and the relation between the distribution of electromagnetic pressure and the configuration of the coil was also analyzed.The spatial distribution of forming pressure in electromagnetic forming could be controlled by the configuration of the coil.It is important that the EM pressure distribution is appropriate for the part that one would wish to form when the coil is designed.Coils were distinguished and expatiated based on their configurations,and their typical applications were presented by demonstrations.
