摘要

为解决地下停车场内车辆通过减速带致使上部楼层竖向振动不满足舒适度要求的问题,提出一种用于楼板结构的车致竖向振动控制的减振装置。基于被控结构—减振带—车辆的一体化有限元模型,以楼板结构竖向振动加速度幅值及车辆荷载幅值为指标,对减振带进行参数优化分析,并通过实地实测验证了所选参数的合理性与减振带的有效性。

Abstract

To solve the problem that structural acceleration induced by vehicles in vertical direction is too large to meet comfort requirements in related codes, a new device named as vibration control humps to be used to replace the conventional speed control humps will be introduced. Parameters of the vibration control humps will be analyzed based on the structure-vibration control humps-vehicle model and taking the amplitude of structural acceleration in vertical direction and vehicle load as analysis indicators. Measured results show that vibration control humps can effectively reduce the vertical vibration of the upper structure induced by vehicle load and structural acceleration can meet the relevant specifications comfort requirements.
