A self-powered magneto-rheological vibration damping device

Abstract

The invention discloses a self-powered type magneto-rheological damping device which comprises an outer barrel, wherein two inner barrels are fixed in the outer barrel, and the insides of the inner barrels are hollow to form damping cavities; a ball screw pair is arranged between the inner barrel, rigid rods are respectively connected to the two ends of the ball screw pair, and the two rigid rodspenetrate through the damping cavities to be connected with an inner wall of the outer barrel; a plurality of blades are fixedly arranged on the parts, in the damping cavities, of the rigid rods, theinner barrels are filled with magneto-rheological fluid, and the outsides of the inner barrels are wound by electrified coils; a movable device connected with the ball screw pair is arranged under theball screw pair, a mass block is arranged in the movable device, steel plates are arranged at the two sides of the mass block, magnets are arranged on a lateral wall of the movable device, and the steel plates are located among adjacent magnets; rotors are in interference fixed connection to the peripheries of the rigid rods, and each rotor is composed of a permanent magnet and a rotor magnet yoke; a stator core is arranged at the periphery of each rotor, a stator winding is arranged on each stator core, a stator shell is fixedly connected to the outside of each stator, and the stator shellsfixedly contact outer walls of the inner barrels.

Description

technical field

[0001] The invention belongs to the field of vibration control of civil engineering, in particular to a self-powered magneto-rheological damping device, which is mainly used in controlling the vibration response of high-rise buildings and towering structures. Background technique

[0002] With the progress of science and technology and the development of society, the development of building structure forms tends to be diversified and complicated, and the sensitivity of high-rise buildings to earthquake or wind load is significantly increased. Environmental vibration can easily induce large lateral vibration and deformation of the main structure, even exceeding the allowable comfort requirements. In recent years, in order to reduce the vibration response of structures, installing reasonable and effective damping systems in high-rise buildings and high-rise structures has received more and more attention.

[0003] At present, according to whether there is exte...
