摘要：
为缓解磁浮系统车轨耦合振动，目前往往采用增大轨道梁质量的方法来降低车轨系统耦合所带来的不利影响，但在研究过程中却忽略轨道梁刚度及车辆运行速度的变化对车桥振动的影响。为此，该文首先介绍磁浮轨道梁结构、特性要求以及车轨相互作用方式；然后采用车辆轨道垂向耦合动力学模型，仿真分析轨道梁刚度和车辆运行速度对磁浮车辆与轨道之间相互作用的影响。研究表明：轨道梁刚度对车轨振动响应影响较大，同时车速的影响也不能忽略。为以后轨道梁设计、安装及分析磁浮车轨相互作用提供一定的参考价值。

Abstract: In order to relieve the coupled vibration between vehicle and track system,increasing of the quality of guideway is often used nowadays to decrease the adverse influence caused by vehicle-track coupled vibration.However,the effect of guideway stiffness and operation speed on vehicle and track vibration is neglected in the researches.In this paper,the maglev guideway's structure,characteristics required and the mode of interaction were introduced firstly.And then,vehicle-track coupled dynamics model was developed to analysis the influence of track beam stiffness and vehicle speed on maglev vehicle-track interaction.The study results showed that the stiffness of track beam impacted the vehicle-track vibration greatly,at the same time the influence of speed also could not be ignored.These conclusions can provide a certain reference value for guideway design,installation as well as analyzing the maglev vehicle-track interaction.
