With the development of society, high-rise buildings and large-span bridges are more and more, and the building is characterized in that strength and rigidity meet requirements, but the vibration frequency of the building is usually lower, and if the natural frequency of the building is improved and the structure is changed, the cost is greatly increased. In addition, some high-rise buildings, tower-type buildings and the like can resonate under the action of wind load to generate large-amplitude swing. In engineering, it is a common way to achieve vibration reduction and suppression by adding tuned mass dampers. A TUNED mass damper (TUNED MASS DAMPER, TMD) is attached to the main structure with a natural frequency close to that of the main structure. When the main structure vibrates, the TMD generates an opposite inertial force, so that the vibration of the main structure is damped. The TMD system can effectively reduce the vibration reaction of the main structure, has obvious control effect on the vibration of the structure, and has wide application prospect in the earthquake-resistant and wind-resistant control of high-rise and high-rise structures.
The current tuning mass damper can not be well fixed in the position in application, and can be accurately used again after the external force is required to reset after the damper is used, if the damper is not reset, deviation can occur, and repeated work is inconvenient. The existing tuned mass damper has obvious vibration damping effect in one direction or two directions, but has low sensitivity to omnidirectional adjustment and unsatisfactory vibration damping effect. The existing tuned mass damper cannot well achieve both transverse and vertical vibration damping. The prior tuned mass damper has insufficient anti-oxidation protection measures for components inside the device, and influences the service life of the device.
