【摘要】 提出第二类可控式TMD-混合水箱系统(CTHTS-Ⅱ)来应对由于结构物频率摄动而导致被动调谐类阻尼器的减振效果下降的问题。对比于第一类可控式TMD-混合水箱系统(CTHTS-Ι),两者在结构物频率减小时的减振效果相当;而在结构物频率增大时,CTHTS-Ⅱ具有比CTHTS-Ι更优的减振控制性能。更多还原

【Abstract】 The controllable TMD-hybrid tank system of the second kind (CTHTS-ΙΙ) is presented to handle the vibration control effectiveness drop of tuned type dampers due to frequency excursion of a structure. As compared with the controllable TMD-hybrid tank system of the first kind (CTHTS-Ι), these two systems can almost achieve an identical performance level when the frequency of a controlled structure decreases; however, CTHTS-ΙΙ performs better than CTHTS-Ι when the frequency of a controlled structure increases.更多还原
