| 摘 要： | 为解决调谐质量阻尼器(TMD)普遍存在的耐久性及参数调谐困难等问题,基于理论及试验研究,在TMD的基础上,利用调谐液体阻尼器(TLD)的优点,研发了新型液体质量双调谐减振器(TLMD)。TLMD减振器是TMD和TLD减振器的复合体,由于流体与固体的耦合作用,TLMD有比两者组合更好的减振效果。TLMD减振器应用于南京大胜关长江大桥吊杆涡振的振动控制中,实桥试验结果显示,在模态质量比仅为8‰左右时,所有被测吊杆的阻尼比均在3.2%以上,个别吊杆甚至达到4.66%,减振效果显著。

| Abstract: | To resolve the common problems of durability and parameter tuning difficulty of the tuned mass damper(TMD) in its application,a new type of the tuned liquid and mass damper(TLMD) was developed on the basis of the TMD and by taking advantage of the tuned liquid damper(TLD) in accordance with the theoretic and test studies.The TLMD is a combination of the TMD and TLD and has a damping effect that is better than that of either the TMD or the TLD owing to the coupling action of fluidity and solidity.The TLMD ha... |
