Rotary eddy current tuned mass damper
The invention discloses a rotary eddy current tuned mass damper which comprises a mass block. The mass block is connected with a spiral steel spring, the spiral steel spring is connected with a lowerbottom plate, a hole is formed in the center of the mass block, a ball screw nut is arranged in the center of the mass block, holes are formed in the centers of an upper magnetic conductive circular plate and a lower magnetic conductive circular plate, and a screw penetrates through the nut and the magnetic conductive circular plates. One rolling bearing is connected with each of the upper portionand the lower portion, the upper rolling bearing is connected with an upper bottom plate, the lower rolling bearing is arranged in the center of the lower magnetic conductive circular plate and connected with the lower bottom plate, a conductor circular plate is connected with the screw, a permanent magnet is connected with the magnetic conductive circular plates, and the upper magnetic conductive circular plate and the lower magnetic conductive circular plate are connected through a support and arranged on the lower bottom plate. By means of the rotary eddy current tuned mass damper, the damping coefficient of a rotary eddy current damping part can be converted into an equivalent axial damping coefficient amplified by multiple times, meanwhile, the damping force can be adjusted by adjusting the distance between the magnetic conductive circular plates and the conductor circular plate, the overall control effect of the damper can be improved, and it is guaranteed that the good vibration reduction effect of the damper is achieved.
