The evacuated tube side-suspended high-temperature superconducting (SS-HTS) magnetic levitation prototype vehicle can run at high speed on a uniform permanent magnet guideway due to the characteristics of magnetic flux pinning. However, permanent magnet guideway with magnetic fluctuations will cause resistance in the running direction of the high-temperature superconducting maglev prototype vehicle, which will inevitably affect its running stability. In order to study the influence of magnetic field gradient and running speed on the magnetic resistance of the high-temperature superconductor in the direction of running, a three-dimensional model is established using the finite element software COMSOL Multiphysics to calculate the magnetic resistance of the high-temperature superconductor when it passes through a permanent magnet guideway. The results show the influence of the magnetic field gradient of the permanent magnet guideway and the running speed of the prototype car on the magnetic resistance to various degrees.

真空管SS-HTS磁悬浮系统运行磁阻的数值模拟与分析

由于磁通钉扎的特性,真空管侧悬式高温超导(SS-HTS)磁悬浮原型车可以在统一的永磁导轨上高速行驶。然而,具有磁波动的永磁导轨会在高温超导磁悬浮原型车的行驶方向上产生阻力,不可避免地会影响其行驶稳定性。为了研究磁场梯度和运行速度对高温超导体在运行方向上的磁阻的影响,使用有限元软件COMSOL Multiphysics建立了三维模型来计算高温超导体的磁阻。高温超导体通过永磁导轨时。
