混合液体质量阻尼器对结构风振控制的研究

Research of Wind Vibration Control with Hybrid Mass Liquid Damper

基于TMD和TLD各自的特点将二者结合为混合液体质量阻尼器(HLMD),此种阻尼器能改善TMD对微弱振动控制时灵敏度低的不足,且具有更强的耗能能力;并对HLMD装置的减振机理和计算模型进行概述,推导出其动力平衡方程。以广东地区某超高层酒店为例进行风振时程分析,对HLMD与TMD控制下的结果进行比较。分析表明:HLMD对结构风振响应控制效率显著,并优于TMD。

Combined the characteristics of TMD and TLD, the hybrid mass liquid damper（HLMD） was prepared, which is more sensitive to weak vibration control and has stronger energy dissipation capacity than TMD. Then the vibra- tion reduction mechanism and calculation model of this devise were summarized. Wind vibration of a hotel in Guangdong was calculated,which controlled by HLMD or TMD separately. The results show that HLMD has a significant effect on the wind vibration control, and better than TMD.
