The monopole permanent magnet railway (PMR) is used in the present high-
T
c
superconducting (HTS) maglev vehicle system. In order to improve the performance of the present maglev vehicle system, many studies have been done to optimize the maglev system. Stiffness is one of the important parameters for maglev vehicle system design. In this article, measurement of the vertical and lateral magnetic force stiffness of HTS bulk arrays above monopole PMR and double-pole PMR are measured. Comparing the experimental results, it is found that the magnetic force stiffness of bulk arrays above double-pole PMR is better than that of monopole PMR. The experimental results show that the running stability of HTS maglev vehicle system using double-pole PMR is much better than that of using monopole PMR.
