结合比例模型的动力试验，系统地描述了磁浮列车系统各子结构的自振特性，在悬浮和行驶状态下结构动态响应，悬浮模块之间的相关特性以及气隙变化，对系统各子结构的耦合振动问题及其起因进行分析，并对如何减小结构响应、控制耦合振动提出解决方法。

Experimental Research onDynamic Characteristics and Coupled Vibration of a Maglev Train System

In this paper, the results of dynamic test conducted on a scaled model of a maglev train system are presented. The resonant characteristics of the sub-structures of the maglev train system, the structural dynamic responses at levitated and running state, coherence of the levitated train body, the variation of the air gaps between the magnets and tracks, and the coupled vibration of the sub-structures are analyzed. Some methods to lower and control the structural dynamic responses and the coupled vibration of maglev systems are put worword
