中文摘要：
为了实现磁浮车的无接触的制动,本文提出一种振动耗能的方法.该方法通过人为使得轨道磁场分布不均衡,从而将运行磁浮车体运动方向上的动能转化为与其垂直方向上的阻尼振动,以消耗运行车体的动能并使车体减速.文中忽略空气阻力,采用理论分析与计算机仿真的方法讨论了轨道磁场分布不均对车体振动特性的影响.最后在西南交通大学真空管道高温超导磁浮系统实验平台上实验验证了该方法对车体运行速度的影响,为将来的真空管道磁浮交通系统的设计提供参考.
英文摘要：
For non-contact braking in maglev train system,an approach to exhaust the kinetic energy of the running maglev by vibration is presented.To achieve this,the distribution of the flux on the top face of the permanent guidway（PMG）is not arranged homogeneously in high temperature superconductivity（HTS）maglev system.The kinetic energy of the maglev on moving direction will be shifted to the vertical direction and to be exhaust for damped vibration.So the velocity on the moving direction will slow down gradually.Ignoring air resistance,the effects of in-homogeneous distribution of the flux on vibration characteristics of maglev system are analyzed theoretically and simulated by software on PC.Then it is verified on an evacuated tube transport（ETT）system of Southwest Jiaotong University.The results demonstrate that this approach to braking on ETT maglev system is reasonable and effective and should be a reference for practical ETT in the future.
