Abstract

The invention provides a liquid damping tuned mass damper. A vibration damping device is mainly composed of slide rails, springs, a liquid storage tank and a rectangular metal pendulum block. Liquid damping can replace hydraulic viscous damping in a traditional TMD (tuned mass damper), and the liquid damping tuned mass damper is suitable for structures such as high-rise buildings, offshore drilling platforms and wind turbines, has a simple structure, is easy to install, and is economical and environment-friendly. A simple device formed by liquid in the liquid storage tank and the rectangular metal pendulum block replaces an expensive damper. The non-linear springs are adopted, and the vibration frequency band is wide. No external energy is required, aiming at the problems that the existingtuned mass damper is sensitive to vibration frequency and has high cost and the like, the non-linear stiffness liquid damping TMD is provided, the spring system part adopts the non-linear springs with a widened frequency band, the damping system part adopts liquid damping, the installation space is reduced, the cost is greatly reduced, and the liquid damping tuned mass damper is economical and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of structural vibration control, in particular to a liquid damping tuned mass damper. Background technique [0002] As the height of buildings increases and the number of offshore drilling platforms increases, these engineering structures are prone to vibration under the excitation of external loads, especially under extreme loads such as strong winds and strong waves, which will lead to structural performance degradation, loss of stability and damage or even collapse. Therefore, a simpler, economical and safer shock absorber is needed. [0003] The tuned mass damper is mainly composed of a mass block system, a spring system and a damping system. Due to its simple structure and low cost, it is widely used in wind and earthquake resistance of large structures. The vibration suppression effect of the damper is very sensitive to the vibration frequency of the structure, and the vibration reduction effect is ob...
