| Abstract: | In this paper,a dynamic interaction model of high-speed maglev vehicle-bridge is established,based on the configuration of German Transrapid high-speed maglev system.Seismic responses of the maglev vehicle-bridge system are simulated for different vehicle velocity and beam span.The effect of vertical coupling dynamic system of the maglev vehicle-bridge on earthquake response is researched for the different vehicle velocity and the beam span,and several significant results and conclusions are obtained. |
