摘　　要：提出了一种新型调谐类阻尼系统——调谐双重液柱/质量阻尼器(TDLCMD),同时提出运用相位差分析方法解析由一个主TLCD与一个次TLCD组合而成的双重液柱水箱内水的动力效应对TDLCMD系统控制性能的影响.推导了结构-TDLCMD系统的运动方程,通过数值模拟研究了不同TLCD水柱长度的TDLCMD系统在风振与地震激励情况下对结构的整体控制性能,对比了相应TMD、TLD、TLCD的控制效果,并对TDLCMD的设置提出了建议.结果表明,TDLCMD经优化设置后可取得与普通TMD相近的控制效果,优于TLD与TLCD.同时,TDLCMD较TMD更经济且更具实用价值.This paper presents a new tuned-type damper system-tuned double liquid columns/mass damper （TDLCMD）. A phasic difference analysis method is also presented to analyze how dynamic effect of water in the double TLCDs system （DTLCD） composed of a major and a minor TLCD-affects the control performance of TDLCMD system. The equation of motion of structure-TDLCMD system is formulated, numerical simulaion conducted and the performances of ordinary TMD, TLD, TLCD and TDLCMD compared under wind and earthquake excitation, respectively. Recommendations for designing a TDLCMD are also provided. Results show that the optimally designed TDLCMD can achieve a performance level close to that of an ordinary TMD, and outperforms TLD and TLCD. As compared with ordinary TMD, the TDLCMD is more economical and practical.
