Abstract
This paper studies the vibration problem of the guideway girder of a high-speed maglev train during a double line intersection. Established a dynamic model of the high-speed maglev train and a finite element model of the double guideway girder pier. Calculated the dynamic response of the guideway girder under different speeds, support stiffness, and intersection conditions. The results show that when the operating speed exceeds 400 km/h, the dynamic response of the guideway girder significantly increases; The mid span deflection and vertical acceleration of guideway girder under intersection conditions are greater than those under unidirectional operation, but the deflection is more sensitive to intersection conditions; The deflection of guideway girder decreases with the increase of support stiffness, and the design of guideway girder should strive to increase the support stiffness as much as possible.
