Vibration Reduction Strategies of Controllable TMD-Hybrid Tanks System

  • Received Date: 05 Sep 2007

  • Excursions of structures’ frequencies,result from engineering vibration or discrepancies between structures’ actual frequencies and designed ones due to calculation or construction errors,will make the vibration reduction effect of a passive tuned damper drop obviously.In order to improve the detuning effect of a passive tuned damper,a controllable TMD-hybrid tanks system(CTHTS) was proposed.Horizontal baffles in this system are switched to deal with the frequency excursion of a structure.The setting of parameters in the system was discussed,and the motion equations for TLCD(tuned liquid column damper),TLD(tuned liquid damper) and a structure with THTS(TMD-hybrid tanks system) are derived.A numerical example was used to compare the control performance of CTHTS and ordinary TMD(tuned mass damper).The research results show the advantage of the CTHTS and the effectiveness of the strategies.
