摘要
研究了超导块材磁体在高温超导磁悬浮车系统中的2种潜在应用。高温超导YBCO块材经过Lakeshore恒磁场充磁机充磁之后,利用高温超导磁悬浮测试装置研究了其在永磁轨道上方的悬浮和导向性能;实验发现2种不同充磁方向励磁的块材磁体表现出明显不同的行为,其中一种对悬浮力帮助比较大,另一种则对导向力帮助比较大。这一结果可以为某些特殊需求(如重载、弯道运行等)的高温超导磁悬浮车系统设计提供一定的实验依据。
In order to further enhance the load capability and stability of present high temperature superconducting maglev vehicle, we investigated two kinds of potential application of superconducting bulk magnet for the vehicle application. The YBCO bulk magnet was magnetized by Field Control Electromagnets Workbench which can produce a constant magnetic field between two magnetic poles. After the magnetization, the levitation and guidance performances of bulk magnet over permanent magnet guideway were investigated. It was found that the bulk magnet with two magnetization directions showed different force behaviors. One was good for improving the levitation force, the other was good for the guidance force. These results provided some scientific analysis for the special designs of the high temperature superconducting maglev vehicle system, such as heavy-load and curve-passing.
