为了设计调谐类阻尼器,基于结构物内部储水装置的多用途性,并结合调谐液柱/质量阻尼器(TLCMD)的经济性与实用性以及混合水箱装置(MTLDs)优越的减振控制性能,提出调谐双重液柱/质量阻尼器(TDLCMD)的概念。分析了由双重调谐液柱阻尼器(DTLCD)组合而成的水箱内水的动力效应对TDLCMD系统控制性能的影响;并提出运用优化动力方法对TDLCMD进行设置。算例分析表明:TDLCMD可取得与TMD相当,优于TLD、TLCD的控制效果;而运用优化动力方法设置的TDLCMD的控制性能明显优于普通方法,并为适应结构物内部使用空间要求提供了更为宽松的条件。
In order to design a tuned class damper, based on the versatility of the internal water storage structure of the structure, combined with the economy and practicality of the tunable liquid column / mass damper (TLCMD) and the superior damping control performance of the hybrid tank units (MTLDs) , Proposed the concept of tuning dual liquid column / mass damper (TDLCMD). The influence of the dynamic effect of water in the tank by the combination of DTLCD on the control performance of TDLCMD system is analyzed. The TDLCMD is proposed to be set up with the optimized dynamic method. The case study shows that TDLCMD can achieve the same control effect as TMD and better than TLD and TLCD. The control performance of TDLCMD with optimized power method is obviously superior to that of common method, and it provides more adaptability to the internal use space of structure For loose conditions.
