摘要

为研究不同型式的40 m简支梁在中低速磁浮列车作用下的动力响应及影响机理，基于40 m简支梁梁轨一体方案和梁上梁方案两种型式，考虑PID主动悬浮控制，采用模态综合理论，建立精细的中低速磁浮列车—简支梁系统动力相互作用理论模型，并基于长沙磁浮试验进行可靠性验证。对两种型式的40 m简支梁在低速磁浮列车作用下的动力响应进行分析及对比，探讨不同桥梁型式对系统耦合振动的影响机理。结果表明：相比于梁上梁方案，梁轨一体方案的竖向动挠度更大、加速度更小，车体竖向位移更大、加速度相近，梁上梁方案更优；桥梁型式对主动悬浮控制系统的影响较微弱；梁上梁方案中简支梁存在丰富的高频局部振动模态，会增大桥梁变形和桥梁、车体的振动优势频率；桥梁型式的不同会通过波长效应、局部振动等影响磁浮列车—轨道—桥梁系统的耦合振动。

Abstract

In order to study the dynamic responses and influential mechanism of 40-metre simply supported beams with different types under the action of low-to-medium speed maglev train

based on the beam rail integration and beam on beam scheme

considering PID active suspension control and adopting modal synthesis theory

a precise dynamic interaction theoretical model of low-to-medium speed maglev train and simply supported beam system is established

and the reliability is verified based on Changsha maglev test. The dynamic response of 40-metre simply supported beams with two different types under the action of low-to-medium speed maglev train is analyzed and compared

and the influential mechanism of bridge types on the coupling vibration of the system is also discussed. The results show that compared with the beam on beam scheme

the vertical dynamic deflection of the beam rail integration scheme is greater

and the acceleration is smaller. The vertical displacement of the car body is more significant

and the acceleration is similar. Comprehensively， the beam rail integration scheme is better. The influence of bridge types on active suspension control system is marginal; in the beam on beam scheme

there are abundant high frequency local vibration modes of simply supported beams

which increases the bridge deformation and the vibration dominant frequency of bridge and vehicle body; type difference can affect the coupling vibration of maglev train-track-bridge system via wavelength effect and local vibration.
