摘要：
In order to explore the coupling vibration characteristics of the medium speed maglev vehicle-trackbridge system, the vehicle was simplified as a multi-rigid body with 45 degrees of freedom. The track-bridge structure was simplified as a double-layer elastic Bernoulli-Euler beam. Then, a coupling vibration analysis model of maglev vehicle-track-bridge system considering track irregularity was established based on proportionintegration- differentiation (PID) suspension active control. A corresponding simulation program was developed to calculate the time domain and frequency domain response of the system and analyze the influence of the vehicle speed and the under-rail equivalent support elastic modulus on the dynamic response of the system. The results are shown. The vibration of the track-bridge structure is closely related to the characteristic frequencies induced by the maglev vehicle. When the vehicle crosses the bridge at the speed of 200 km/h, the vibration of the track- bridge structure between 65 and 150 Hz performs as the local vibration of the F-rail. The displacement amplitude of track-bridge structure does not change monotonically with the increase of vehicle speed, since the vehicle speed changes the characteristic frequency of vehicle load. The resonance would occur when the characteristic frequency of vehicle load is close to the natural frequency of the track-bridge structure. The relationship between the vehicle acceleration amplitude or stationarity index and the vehicle speed is also non-monotonic. The change of the under-rail equivalent support elastic modulus has little effect on the vertical displacement amplitude of bridge, but has great effect on the vertical displacement amplitude of F-rail and the vertical acceleration amplitude of vehicle. The present results can provide references for further coupling vibration research and track structure design of medium speed maglev system. © 2023, Central South University Press.
