Single-side tensioning prestress self-balancing type inertial-capacitance damper

Abstract

The invention relates to a single-side tensioning prestress self-balancing type inertial-capacitance damper. The single-side tensioning prestress self-balancing type inertial-capacitance damper is used for being connected with a vibration structure through a stay rope and comprises an outer cylinder, a spring, a positive and negative thread lead screw, a magnet disc, a conductor disc, a first connecting assembly and a second connecting assembly, wherein the spring, the positive and negative thread lead screw, the magnet disc and the conductor disc are coaxially arranged in the outer cylinder,and the first connecting assembly and the second connecting assembly are fixedly connected with the inner side wall of the outer cylinder; one end of the spring is fixedly connected with the outer cylinder, and the other end of the spring is connected with one end of the positive and negative thread lead screw; the other end of the positive and negative thread lead screw is used for being connected with the vibration structure through the stay rope; threads opposite in direction are formed in the two ends of the positive and negative thread lead screw correspondingly; the magnet disc is arranged on the thread at one end of the positive and negative thread lead screw in a sleeving manner through the first connecting assembly; and the conductor disc is arranged on the thread at the other endof the positive and negative thread lead screw in a sleeving manner through the second connecting assembly. Compared with the prior art, the single-side tensioning prestress self-balancing type inertial-capacitance damper has the beneficial effects of being convenient to install, capable of achieving self balancing, capable of achieving resetting and the like.

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...

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
