Problems solved by technology

At present, although the screw-screw rotary eddy current damper has a certain speed amplification capability, the screw-screw rotary eddy-current damper must use the fixed end to limit the rotation of the screw and the stator at the same time, so that the damper can play a role , which makes it impossible to use in a pure tension system with unilateral tension, and the connection of the cable cannot provide such a braking torque

Abstract

The invention relates to a unilaterally tensioned prestressed self-balancing inertial capacity damper, which is used to connect with a vibration structure through a cable, including an outer cylinder, springs coaxially arranged in the outer cylinder, and positive and negative screw rods , a magnet disk, a conductor disk, and a first connection assembly and a second connection assembly that are fixedly connected to the inner wall of the outer cylinder, one end of the spring is fixedly connected to the outer cylinder, and the other end is connected to one end of the positive and negative thread rod, so The other end of the positive and negative thread rod is used to connect with the vibration structure through the cable, the two ends of the positive and negative thread rod are respectively provided with threads in opposite directions, and the magnet disk is sheathed through the first connecting component On the thread at one end of the positive and negative screw rod, the conductor disk is sleeved on the thread at the other end of the positive and negative screw rod through the second connecting component. Compared with the prior art, the present invention has the advantages of convenient installation, self-balancing , Can be reset and so on.

Description

technical field [0001] The invention relates to the field of vibration control of civil engineering structures, in particular to a unilaterally tensioned prestressed self-balancing inertial capacity damper. Background technique [0002] As a new and efficient structural passive vibration control means, the inertial damper is an energy-dissipating vibration-reduction device made of the damping effect of eddy currents. It has non-contact, no mechanical friction and loss, no lubrication, long service life and Easy installation and other advantages. At present, the eddy current damper is mainly used as the damping element of the tuned mass damper and is gradually being applied in the field of passive vibration control of civil engineering structures. [0003] The generation of eddy current damping must have a conductor plate for cutting the magnetic induction line movement, that is, there is relative motion between the magnetic field source and the conductor plate, and the magn...
