| 摘 要： | 结合工程实际,介绍了结构振动控制方法,并研究液体质量双调谐阻尼器(TLMD)及杠杆质量减振器(LMD)等新型阻尼减振系统.室内及实桥试验表明:由于兼具调谐质量阻尼器(TMD)与调谐液体阻尼器(TLD)的优点,TLMD便于调谐,减振效果与耐久性更好.理论及室内试验证明:与现有减振措施相比,LMD对桥梁景观的不良影响小,易于安装、养护,且减振效果更好,是一种更适于超长斜拉索振动控制的"广谱"减振器.

| Abstract: | In the light of the engineering practice, the vibration control methods for civil engineering structures are presented and the new type damping systems, such as the tuned liquid and mass damper (TLMD) and the lever mass damper (LMD) , are studied. The tests completed in laboratory and on bridges in the field show that the TLMD is easier to be tuned and has better vibration damping effect and durability because it takes both the advantages of the tuned mass damper (TMD) and the tuned liquid damper (TLD). The theories and laboratory tests also prove that in comparison to the existing vibration damping measures, the LMD has little adverse influence on the bridge aesthetics, is easy to be installed and maintained, has better vibration damping effect and is a kind of "broad-spectrum" damper that is more suitable for vibration control of very long stay cables. |
