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.
