摘要: 以惯容系统及双层轨道交通车辆段上盖建筑为研究对象，建立并验证有限元模型，探究不同类型及惯质比的惯容系统对车辆段上盖建筑振动控制的效果。结果表明，黏滞惯容阻尼器(VMD)、调谐惯质阻尼器(TID)和调谐黏滞质量阻尼器(TVMD)等3种惯容系统均能有效降低上盖建筑各楼层的Z振级，且随着惯质比的增大，减振效果越显著。不同惯质比的TID和TVMD的Z振级减小幅值较大，可达1 dB~3 dB；而VMD减振效果相对较弱，Z振级减小幅度约1 dB。Abstract: Focusing on inertance systems and double-deck rail transit vehicle depot superstructure buildings, a finite element model was established and validated, the effectiveness of different types and inertance-to-mass ratios of inertance systems in controlling the vibration of these superstructure buildings was investigated. The results indicate that the three types of inertance systems viscous mass damper (VMD), tuned inerter damper (TID) and tuned viscous mass damper (TVMD) can all effectively reduce the Z-weighted vibration level on each floor of the upper building, and the damping effect becomes more pronounced as the inertance-to-mass ratio increases. Inertance systems TID and TVMD with different inertance-to-mass ratios exhibit larger reductions in the Z-weighted vibration level, reaching 1 dB~3 dB; whereas VMD shows relatively weaker damping performance, with a reduction in the Z-weighted vibration level of approximately 1 dB.
