Tuned mass damper (Tuned Mass Damper) is called for short TMD, is to add inertia mass at towering top of tower or position, top, and is equipped with spring and links to each other with agent structure (towering tower) with damper.The vibration frequency of tuned mass damper is near the frequency of main structure, control strategy reaches the purpose of dynamic absorber for using minor structure and the resonance of the main structure control vibration shape, the energy that the application damping structure constantly consumes main structure and minor structure reduces the dynamic response of main structure.Yet about the application of the tuned mass damper that is used for towering tower vibration damping seldom, and effectiveness in vibration suppression is also bad in the prior art.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the prior art, the invention provides a kind of tuned mass damper for towering tower vibration damping, it is arranged in top or the top of tower body, comprise: mass, damping system, spring system, described mass links to each other with damping system, spring system respectively, and by hanging or supporting removable.
Further, described tuned mass damper for towering tower vibration damping also comprises redundancy protection systems, and structure is played the safeguard protection effect.
Further, described i-shaped beams is fixed on the tower body by the first backing plate, and mass is suspended on by round-link chain can be along on the roller system of i-shaped beams rolling; Increase the effective travel of tuned mass damper and improve damping efficiency along the combination that i-shaped beams rolls by round-link chain swing and roller system.
Further, described redundancy protection systems is that the round-link chain of arranged for redundancy between described mass and the roller system is to play the safeguard protection effect to structure.
Further, the other end of described damping system and spring system is connected to the fixing rigid support in the close described tower body of i-shaped beams below or is fixed on the tower body by the second backing plate and gripper shoe.
Further, but described mass by the rolling bearing system at the track rolling support, the rolling bearing system is comprised of roller, axle, bearing support.
