The invention discloses an energy recovery type eddy current damper. The energy recovery type eddy current damper comprises an outer cylinder, the outer cylinder is provided with a ball screw pair, agroove and mass blocks. The ball screw pair includes a screw rod, a nut and a plurality of balls. A circulation passage is formed between a screw rod portion and the nut, and the balls are disposed inthe circulation passage. A plurality of steel plates are fixedly arranged on the outer circumference of the nut, and damping chambers fixed on the bottom plate of the outer cylinder are arranged at the lower portions of the steel plates. A magnet is arranged inside each damper chamber, the magnetic poles of the magnet are staggered, and a gap for passing the steel plate is left between adjacent magnets, and a coil is wound around the magnet. A rigid rod is fixed to one end of the screw rod, and the other end of the rigid rod is fixed on the outer wall of the groove. Mass blocks are arranged inside the groove, and a guide rod is arranged in a direction perpendicular to the screw rod. The guide rod penetrates through a through hole in the middle of the mass blocks and the two ends of the guide rod are fixed on the inner wall of the groove. Springs are arranged on the inside of the groove, and the two ends of the springs are respectively fixed on the inner walls of the groove and the mass blocks.
Description
technical field [0001] The invention belongs to the field of vibration control of civil engineering, and in particular relates to an energy recovery type eddy current damper, which is mainly used in controlling the vibration response of high-rise buildings and towering structures. [0002] technical background [0003] Traditional structural strength design methods resist external forces by enhancing the structure's own resistance. With the continuous advancement of science and technology, the ability of human beings to resist various natural disasters has been continuously improved. In recent years, vibration control technology has become a new research hotspot in the field of seismic resistance of building structures. It uses structural vibration control theories and methods to strengthen structures. anti-vibration ability. [0004] Structural vibration control technology can be divided into passive control, active control and semi-active control according to whether the c...
