摘要

车轨耦合振动是磁浮列车运行中面临的一个重要问题，文章基于一种新型中低速磁浮走行机构，对其车轨耦合振动响应进行分析，判断其结构的合理性。为了分析新型磁浮列车的“车辆-轨道梁”的耦合振动响应，基于Simpack、Simulink和ANSYS等相关软件平台建立了“车辆-控制-轨道梁”耦合动力学模型，对不同速度下的车轨耦合动力学响应进行数值仿真，获得耦合系统的动力学响应特征、速度对耦合系统动力学响应规律的影响，并对响应特征中出现的特殊响应现象进行分析。结果表明，随着速度的提高，轨道梁、悬浮模块和车体的动力学响应越剧烈，当速度在100 ~120 km/h时，耦合系统出现共振现象，同时存在于横向和垂向2个方向。此外，由于新型悬浮架独特的结构特点，会出现走行机构中部横向动力学响应大于端部的特殊响应情况。

Abstract

Vehicle-guideway coupling vibration is an important issue in the operation of maglev trains. In this paper

based on a new medium-low speed maglev running mechanism

the vehicle-guideway coupling vibration response was analyzed to determine the rationality of its structure. In order to analyze the vehicle-guideway coupling vibration response of the new maglev train

the vehicle-control-guideway coupling dynamic model was built by using Simpack

Simulink and ANSYS. Numerical simulations of vehicle-guideway coupling dynamic response at different speeds were performed

based on which the dynamic response characteristics of the coupling system and the influence of the speed on the dynamic response law of the coupling system were obtained

and the special response phenomena in response characteristics were analyzed. Results show that

with the increase of the speed

the dynamic responses of the guideway

levitation module

and carbody become more intense. When the speed is 100-120 km/h

resonance exists in the coupling system

both in lateral and vertical directions. In addition

due to the unique structural characteristics of the new levitation bogie

the lateral dynamic response in the middle of the running mechanism is larger than that at the end.
