摘　　要：电磁铆接技术是电磁成形与传统铆接相结合发展起来的一种装配技术,在复合材料结构连接以及大直径难变形铆钉室温铆接方面具有显著优势,具有广阔的应用前景。综述了电磁铆接设备、铆接过程数值仿真技术以及工艺试验3个方面的研究进展,并结合笔者相关研究结果对目前基础研究方面存在的问题进行了简要分析。设备研究方面,重点分析了国内外电磁铆接设备的发展阶段和技术水平,分析表明国外电磁铆接技术仿真较早,而且设备与工艺方法相对比较成熟,而国内研究虽然取得了一定进展,与国外相比仍有很大差距。数值仿真方面,通过对比着重介绍了电磁铆接工艺仿真主流方法的优缺点,可根据自身需求进行选择。工艺试验方面,国内近些年关于该工艺基础研究报道较多,但工艺研究方面无统一的标准和规范,要想使该技术快速得到工程应用仍需长期研究与探索。Electromagnetic riveting(EMR)is an assembly technology developed from the combination of electromagnetic forming and traditional riveting.The technology has obvious advantages in joining composite structures and riveting large-diameter/hard-to-deform rivets at room temperature.In this paper,the development achievements of electromagnetic riveting technology at home and abroad are summarized and analyzed from three aspects of electromagnetic riveting equipment,numerical simulation methods and process tests.The analysis results showed that the simulation of electromagnetic riveting technology abroad is earlier,and the equipment and process methods are relatively mature.Domestic research has made some progress,but compared with abroad still has a big gap.In terms of numerical simulation,the advantages and disadvantages of the mainstream methods of electromagnetic riveting process simulation are highlighted by comparison,which can be selected according to needs.In recent years,there are many reports on basic research of this technology in China.But there is no consistent standard and specification in the research of equipment and technology.It still need long-term study and exploration if this technology want to be quickly applied in engineering.
