| 摘 要： | 工程振动使结构物的固有频率发生偏移,导致被动控制装置调谐质量阻尼器(TMD)、调谐液体阻尼器(TLD)或调谐液柱阻尼器(TLCD)的减振效果明显下降.鉴于此,提出了可控式TMD-DTLCD混合调频系统(Controllable TMD-DTLCD Hybrid System,简称CTDHS)的概念,并以被动控制的形式研究了本系统应对结构物频率发生偏移情况下的减振控制策略.介绍了本系统各参数的设置方法,TMD、TLCD以及结构-CTDHS系统的运动方程,并通过算例中CTDHS与普通TMD对结构减振效果的对比,证明了CTDHS的优越性以及减振策略的有效性. |

| Abstract: | Excursion of structural frequency happens due to engineering vibration, which makes the vibration reductioneffect of passive control devices such as tuned mass damper (TMD), tuned liquid damper (TLD) or tuned liquid columndamper (TLCD) drop obviously. In view of this, a controllable TMD-DTLCD hybrid system (CTDHS) is presented forthe first time, and the control strategies of this system are studied in the passive form to handle the frequency excursion ofa structure. The setting of the system parameters and the equations of motion of TMD, TLCD as well as structure-CT-DHS are also introduced. Through an algorithmic example, the vibration reduction effects of CTDHS and ordinary TMDare compared to prove the advantage of the CTDHS and the validity of the strategies. |
