Abstract
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 on-board 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 high-strength 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.
