Abstract

In practical application of a High-Tc Superconducting (HTS) maglev vehicle, the onboard HTS bulks are inevitably exposed to a varying inhomogeneous field due to present processing and assembling technology of the permanent magnetic guideway (PMG). To explore the influence on the levitation forces of YBa2Cu3O7-x bulk samples in such changing external magnetic field due to different traveling speeds, we experimentally investigated the general transition of said levitation force under such varying external field simulated by a spinning circular PMG. The force waves general attenuated caused by AC loss brought by magnetic field fluctuating. For further information on that levitation dynamic equilibrium, we study experimentally the wave detail and general transition of the dynamic levitation force under different steady velocities between 0 and 120 km/h. Ultimately the results indicated that the attenuation saturated rapidly in higher speed that would be of benefit to the HTS-PMG system in long-term operating.
