摘要

摘要: 为了使真空管道高温超导(HTS)侧浮列车获得更高的起动推力和运行加速度,提高列车高速运行时的稳定性,以真空管道HTS侧浮列车驱动系统为研究对象,建立了直线电机2D仿真模型,在此基础上,采用有限元软件仿真和设计实验,对不同次级下的电机起动推力及法向力特性进行了研究.研究结果表明:不同次级材质及厚度对列车运行有着明显影响,当列车以较高同步速度运行时,选择厚度为2 mm左右的工业纯铝作为电机次级,列车能获得较高的起动推力和加速性能,同时铝次级的低密度特性降低列车总重,并在悬挂方向上提供一定的悬浮力,提高了列车运行的稳定性.

Abstract: In order to gain a greater starting thrust and higher running acceleration in evacuated tube HTS (high temperature superconductor) side-suspended maglev vehicle, and improve running stability at high speeds, a 2D simulation model for linear motor was established by studying the driving system of evacuated-tube HTS side-suspended maglev. The characteristics of the starting-thrust and normal force of the motor with different secondary plates were studied by finite element simulation and experiments. The results show that the secondary plates of different materials and thicknesses have significantly effects on the operation of maglev vehicle. When a 2 mm-thick commercial-purity aluminum plate was used as the motor secondary, the maglev vehicle could achieve higher starting thrust and accelerating performance with a high synchronous-speed. Meanwhile, low density of aluminum plate reduces the total weight of the maglev vehicle and it provides a levitation force in the hanging direction, which increases the running stability of the maglev vehicle.
