Multilayer unidirectional tuning liquid column damper
The invention relates to a multilayer unidirectional tuning liquid column damper. The damper is a box body which is integrally in a U shape, wherein the box body is formed by enclosing a plurality of U-shaped plates which are stacked from inside to outside and do not make contact with one another and U-shaped end plates located on the two sides of all the U-shaped plates; a baffle is arranged at the horizontal section of each U-shaped plate; every two adjacent U-shaped plates and the end plates on the two sides form a U-shaped cavity; each U-shaped cavity is filled with liquid to form a liquid column; the U-shaped cavities are independent of one another; and the tops of the U-shaped cavities are open and located on the same horizontal plane. According to the multilayer unidirectional tuning liquid column damper, on the basis of an existing unidirectional tuning liquid column damper, the damping effect is improved in the mode that the U-shaped plates are stacked, the tuning frequency bandwidth can be increased so that the multi-order vibration mode of the structure can be controlled at the same time, and the quality of the liquid in the damper can be improved so that the control efficiency of a certain order of vibration mode can be improved; and the natural vibration frequency of the unidirectional tuning liquid column damper is easy to adjust, and installation and maintenance are convenient.
本发明涉及一种多层单向调谐液柱阻尼器，该阻尼器为整体呈U型的箱体，该箱体由多个由内至外层叠放置但不接触的U型板和位于所有U型板两侧的U型端板围合而成；各U型板的水平段处分别设有挡板，各相邻的两U型板和两侧端板分别形成一U型腔体，各U型腔体内分别填充有液体形成液柱，各U型腔体之间彼此独立；各U型腔体的顶部开敞且位于同一水平面上。本发明在现有的单向调谐液柱阻尼器的基础上，通过层叠设置U型板的方式，实现了阻尼效果的提升，能扩大调谐频带宽度以同时控制结构的多阶振型，也可以增加阻尼器中液体的质量以提高某一阶振型的控制效率；本单向调谐液柱阻尼器的自振频率易于调节，也便于安装维护。
