调谐双重液柱与质量阻尼器及其工程设置方法

Tuned double liquid column and mass damper and their engineering setting method

为了设计调谐类阻尼器,基于建筑物内部储水装置的多用途性,并结合调谐液柱/质量阻尼器(TLCMD)的经济性与实用性以及混合水箱装置(MTLDs)优越的减振控制性能,提出调谐双重液柱/质量阻尼器(TDLCMD)的概念。分析了由双重调谐液柱阻尼器(DTLCD)组合而成的水箱内水的动力效应对TDLCMD系统控制性能的影响;并提出运用优化动力方法对TDLCMD进行设置。算例分析表明:TDLCMD可取得与TMD相当,优于TLD、TLCD的控制效果;而运用优化动力方法设置的TDLCMD的控制性能明显优于普通方法,并使该阻尼器的安装更为适合于建筑物内部的使用空间。

Based on multipurpose property of storage water equipment inside a structure,the tuned double liquid columns/mass damper（TDLCMD） is developed.It combines the practical and economical property of the tuned liquid column/mass damper（TLCMD） and the excellent vibration reduction performance of multiple tuned liquid dampers（MTLDs）.The dynamic effect of water in the tank composed of double TLCDs（DTLCD）,which affects the control performance of TDLCMD system,is analyzed.An optimal dynamic method is also proposed to set the TDLCMD.Numerical analysis results show that TDLCMD set can achieve an effectiveness level close to that of an ordinary TMD,and outperform TLD and TLCD.On the other hand,the control performance of TDLCMD set by optimal dynamic method is much better than that set by normal method.The design of TDLCMD dimension set by the optimal dynamic method is more reasonable for structural internal usage.
