摘要

在面对大跨度楼盖因人引起的竖向振动问题时，采用多重调谐质量阻尼器（MTMD）可有效控制结构振动响应。目前，在MTMD参数优化方面的研究已经很完善，但在位置优化方面尚无一个行之有效的方法。为此，分析了楼盖-MTMD运动方程中的位置相关项，研究了位置在MTMD减振控制中的参与途径，结合有限元法和振型分解法提出了MTMD位置优化方法，在此基础上制定了MTMD参数与位置联合优化策略。最后，以某张弦梁-混凝土板组合楼盖为例进行了MTMD参数与位置设计，比较了不同优化方法下减振体系的减振效果。结果表明，经联合优化策略优化的MTMD拥有更佳的减振性能，可应用于同类大跨楼盖MTMD控制参数设计。

Abstract

Multiple tuned mass dampers (MTMDs) can effectively control the floor vertical vibration caused by pedestrian’s loads. The research on MTMD parameter optimization has been mature, but there is no effective method in MTMD position optimization. Based on the dynamic coupling equation, the participant approach of the position-related terms in the MTMD vibration control was investigated. The finite element method and the modal analysis method were used to construct the combined optimal method of MTMD parameter and location. Comparison of the acceleration for a floor equipped with MTMD designed by the combined and the parameter optimization shows that the proposed MTMD has better damping performance than the parameter optimal MTMD.
