Vibration Characteristics Analysis of the Maglev Vehicle–Switch



Coupling vibration of Maglev vehicle system directly affected the comfort and safety of the train. Aim at vibration issue when the Maglev vehicle get through the switch generated. In the paper, the vibration transfer of vehicle-switch is researched to use experiment approach. The model parameters of switch are measured to apply impact hammer. The vibration spectrum of the maglev train dynamic on-line measurement is analyzed. The natural frequency of track beam is aroused when maglev vehicle diver on the switch in the initial condition. So the coupling resonance caused between vehicle and switch. After improving the turnout stiffness, the resonance phenomenon disappears and the vehicle can be smoothly through the orbit switch.
