Impact of Different Configurations of Permanent Magnet Track on Its Magnetic-Field Distribution

针对高温超导体具有良好的自稳定磁悬浮特性,为促进高温超导体在磁悬浮轨道领域的应用,通过实验研究了永磁轨道磁路块的不同组合方式对其磁场分布的影响,分析了在永磁轨道不同组合方式下的磁场分布时超导列车所出现的平稳运行、倾斜、震荡、停止运行等一系列工况,根据实验结果设计建立了一种可实现不同状态的磁悬浮列车轨道演示模型,为高温超导磁悬浮应用系统的设计提供实验依据。

High temperature bulk superconductors( HTS) have the excellent character of self-stabilizing magnetic levitation. To promote its application in the magnetic levitation track field,the paper studies the influence of different configurations of permanent magnet track on its magnetic field distribution through experiments,analyzes a series of working conditions of maglev such as stable operation,tilting,vibration,and stopping,and finally establishes a small HTS maglev model for the demonstration of interaction properties between the high temperature bulk superconductor and different magnet configurations,which can provide the experimental basis for the design of high temperature superconducting maglev application system.
