Maglev vehicle/elevated-beam guideway vertical coupling dynamics

Elevated guideway is applied widely in maglev railway system for high speed ground passenger transportation. There are two kinds of elevated beam structures in German Emsland Maglev Test Line--the concrete simply supported beam and the double span continuous steel beam. In this paper, the maglev vehicle/elevated beam guideway vertical coupling dynamic model is built in consideration of the two type of beams, and dynamic responses are calculated and compared for different material, beam structure and vehicle velocity. Then, the coupling dynamic response basic laws are obtained to optimize maglev system parameters for better ride quality and smaller beam impact. Finally, the dynamic responses of Qingcheng Mountain maglev system in Chengdu are simulated.
