Abstract

The invention relates to a semi-active tuned liquid damper. The semi-active tuned liquid damper comprises a damper water tank, a regulating water tank and a servo control system; wherein the damper water tank is composed of a box I, a damping net and tuned liquid; the regulating water tank is composed of a box II and regulating liquid; the servo control system is composed of a single-chip circuit board, an acceleration sensor, a liquid level sensor, a water pump I and a water pump II. The frequency of the tuned liquid damper is determined by the liquid level of the tuned liquid. According to the semi-active tuned liquid damper, the liquid level of the tuned liquid can be adjusted through the servo control system to achieve precise control of the frequency of the tuned liquid damper. Compared with the prior art, the semi-active tuned liquid damper can realize the precise adjustment of the frequency of the tuned liquid damper, the damping effect is improved, the design of the damper is simplified, and the damper is good in control effect, simple in structure, easy to maintain and install, good in durability and the like.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and vibration control, in particular to a semi-active tuning liquid damper. Background technique [0002] In today's society, tuned liquid dampers have been widely concerned because of their advantages such as small changes to the original building structure, convenient construction, convenient material acquisition, and significant vibration control effects, and have been widely used in engineering practice. However, the traditional tuned liquid damper has the disadvantage of tuning sensitivity to frequency. Not only the self-damage of the building structure will affect the vibration reduction effect of the tuned liquid damper, but sometimes its own characteristics, such as the volatilization of the liquid, the damping network Corrosion, etc. will also affect its control effect. Moreover, there is a discrepancy between the estimated natural frequency of the structure at design time and ...
