摘　　要：电磁霍普金森(E-Hopkinson)杆实验技术是利用电磁驱动的方式替代了传统霍普金森杆中子弹撞击加载杆来产生应力波,是电磁驱动技术与霍普金森杆实验技术相结合而发展起来的一种新的动态加载技术.本文综述了E-Hopkinson杆实验技术在单轴单向/双向及动态双轴对称压缩/拉伸、复合材料的层间断裂、金属动态包辛格效应等领域的应用现状,涵盖了实验研究,理论分析及数值模拟等,最后对该实验技术未来发展方向进行了展望.The e-Hopkinson bar test technology is a new dynamic loading technology developed by combining the electromagnetic drive technology with the Hopkinson bar test technology,which replaces the traditional Hopkinson bar with the bullet hitting the loading bar to generate stress waves.In this paper,the application status of e-Hopkinson bar test technology in uniaxial unidirectional/biaxial and dynamic biaxial symmetric compression/tension,interlaminar fracture of composites,dynamic bauschinger effect and other fields are reviewed,including experimental research,theoretical analysis and numerical simulation.Finally,the future development direction of e-Hopkinson bar test technology is prospected.
