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.
A new type of tuned damping system - tuning double liquid column / mass damper (TDLCMD) is proposed. Meanwhile, the phase difference analysis method is proposed to analyze the water in a double liquid column tank composed of one main TLCD and one sub-TLCD Dynamic effects on the control performance of TDLCMD system.The equations of motion of the structure-TDLCMD system are deduced.The numerical control of TDLCMD system with different TLCD water column length under wind and earthquake excitation is studied by numerical simulation, TMD, TLD and TLCD, and put forward suggestions on the setting of TDLCMD.The results show that TDLCMD can get the similar control effect to normal TMD after optimization, which is better than TLD and TLCD.At the same time, TDLCMD is more economical than TMD More practical value.
