摘要

MR-TMD阻尼器是在调谐质量阻尼器(TMD)的基础上与磁流变阻尼器(MR)联合使用的一种新型结构半主动振动控制装置。在考虑轨道不平顺的影响下，建立了列车-桥-阻尼器耦合动力学模型。采用自主研发的高速铁路车-桥-轨动力耦合仿真分析平台(TDBCA1.0)，以德国ICE3高速列车通过(80+128+80)米连续箱梁桥为例，分析了轨道不平顺对桥梁振动的影响，比较了TMD阻尼器和MR-TMD阻尼器的减振效果。结果表明，轨道不平顺对桥梁竖向位移影响较小，对桥梁振动加速度影响较大，列车速度越快，对桥梁振动加速度的影响越大。MR-TMD阻尼器对连续箱梁位移峰值影响较小，但能在很大程度上控制振动加速度。MR-TMD减振效果优于TMD阻尼器。

Abstract

MR-TMD is a new type of semi-active control device which combines a Tuned Mass Damper (TMD) and a Magneto Rheological (MR) Damper. In this paper, a dynamical model for Train-Bridge-Damper coupling vibration system is established considering the track irregularities. Based on the self-developed computational software (TDBCA1.0) for coupling vibration of rail vehicle-bridge-track system, take the example of German ICE3 high-speed railway train passing (80+128+80)meters continuous box girder bridge, the relations between the bridge vibration and track irregularities are investigated. Effects of vibration control with TMD and MR-TMD on the bridge are also analyzed. The results shown that the effect of track irregularities on vertical displacement of the bridge is small and on vibration acceleration is large. The higher the train speed is, the larger the track irregularities effect on the vibration acceleration. The maximum displacement of the bridge is impacted little by MR-TMD, but the vibration acceleration is effected obvious, and MR-TMD is effective than TMD in reducing the vibration of the bridge.
