Experimental Research on Dynamic 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 ofthe sub-structures are analyzed. Some methods to lower and control the structural dynamic responses and the coupled vibration of maglev systems are putworword
