摘　　要：为提高真空管道高温超导(HTS)磁悬浮列车系统的自由悬浮运行速度,提出了侧浮式高温超导磁悬浮系统.通过实验对该系统环线运行下的动态过程进行了研究,结果表明,磁浮车在环线运行中,因离心力和重力作用产生横向位移和垂直位移,通过实验和仿真研究了该动态过程对直线电机驱动性能的影响,结果表明,随着垂直位移和横向位移的减小,直线电机起动推力逐渐增大;当垂直位移为5 mm,横向位移小于10 mm时,磁浮车偏离电机中心引起的驱动力变化影响不大.使列车保持较高的驱动稳定性,为侧浮式真空管道高温超导磁浮车初始悬浮位置设计提供参考.In order to improve the speed of the vacuum pipe freely suspended HTS maglev train system, the sidesuspended HTS maglev system have been proposed. Through the dynamic process of the system loop experiments were run under study. The results showed that, the maglev car in the loop operation produced lateral and vertical displacement due to the centrifugal force and the gravity. Through experiments and simulations we study the impact of the dynamic process of the linear motor drive performance. The results showed that the starting thrust of linear motor increases with the decrease of vertical displacement and lateral displacement. While the vertical displacement was 5 mm and the lateral displacement was less than 10 mm, the change of driving force caused by Maglev vehicle deviates from the center of the motor has little effect. The study helps to maintain high driving stability, and provides a reference to design the position of initial suspension of side-suspended HTS maglev vehicle.
