电动悬浮列车具有速度高、悬浮间隙大、安全系数高等优点,在超高速磁悬浮列车领域具有十分光明的应用前景.车载超导磁体是超导电动悬浮列车的核心组成部分之一,其服役可靠性是列车安全运行的重要基础.本文系统地阐述国内外电动悬浮列车的发展历史及现状,针对国内外电动悬浮系统中车载超导磁体的结构和技术方案进行对比和总结.高温超导磁体技术已经成为超导电动悬浮领域的重要发展方向,在列车行驶过程中车载超导磁体系统的热稳定性和振动稳定性是影响其可靠服役的重要因素.高温超导磁体闭环运行技术、轻量小型化低温系统结构设计、高强度低漏热支撑结构设计等将是未来超导电动悬浮系统中车载超导磁体需要重点研究和解决的关键技术难题.
The electrodynamic suspension(EDS)train has the advantages of high speed,large suspension gap,and high safety factor.It has a bright application prospect in the field of ultra-high-speed maglev trains.The onboard superconducting magnet is one of the core components of the superconducting EDS train,and its reliability in service is the basis for the safe operation of the train.In this paper,the development history and status of EDS trains in China and abroad were summarized,and the structure and technical solutions of on-board superconducting magnets in global EDS systems were compared and summarized.The high-temperature superconducting(HTS)magnet technology has become an important development direction in the field of superconducting EDS.The thermal and vibration stability of the on-board superconducting magnet system during the running of the train is an important factor affecting its reliable service.The closed-loop operation technology of HTS magnets,the structural design of lightweight and miniaturized cryogenic systems,and that of highstrength and low heat leakage support devices will be the key technical problems that need to be studied and solved for the on-board superconducting magnets in superconducting EDS systems in the future.
