摘　　要：永磁轨道是高温超导磁悬浮车的重要组成部分之一,对YBCO块材在两种应用场:单峰永磁轨道和双峰永磁轨道上的磁悬浮性能进行了数值和实验研究。通过对比两种轨道上方的切向和法向分量的磁场分布,对实验结果进行了分析。实验发现YBCO块材在双峰轨道上方,悬浮力和导向力均大于单峰轨道,双峰轨道在磁利用率方面高于单峰轨道。The permanent guidway is one of the necessary conditions of high - temperature superconducting maglev train. The experiment and simulation of the two applied magnet field of single - peak and dual - peak permanent magnet guidways were involved in this paper, the different levitation performance of YBCO above single -peak and dual -peak permanent magnet guidways were investigated and by comparing and analysing the horizontal and vertical magnetic field over them, the result of the experiments was explained. The results show the levitatian and guidence force of YBCO on the peak of the dual - peak permanent magnet guidway is larger than that on single - peak one, and so does the utilization rate.
