Eddy current type particle inerter damper

Abstract

The invention relates to an eddy current type particle inerter damper. The eddy current type particle inerter damper comprises a simple pendulum damping unit and a particle inerter unit which are connected through a gear transmission assembly, and swing of the simple pendulum damping unit can be transmitted to the particle inerter unit through the gear transmission assembly; the simple pendulum damping unit comprises a simple pendulum damping unit box body and a simple pendulum mass body, the simple pendulum mass body is arranged in the simple pendulum damping unit box body in a swinging mode,the upper end of the simple pendulum mass body is connected with the gear transmission assembly, and a permanent magnet is arranged on the simple pendulum mass body; and a conductor plate corresponding to the permanent magnet is arranged on the inner wall of the simple pendulum damping unit box body, and the simple pendulum mass body generates an eddy current damping effect when swinging. Energyconsumption can be tuned through the simple pendulum mass body, energy consumption can further be achieved through particle collision and elasticoplastic deformation, multiple energy consumption mechanisms are achieved, in addition, the particle collision efficiency is improved through the inerter amplification effect, and thus the vibration reduction and energy consumption effect is better.

Description

technical field [0001] The invention belongs to the field of vibration control of civil structures, in particular to an eddy current type particle inertial capacity damper. Background technique [0002] At present, in the field of civil engineering, structural vibration control technology plays an important role in anti-seismic and wind resistance. Among them, the development of passive control technology is relatively mature, and it is widely used in engineering because of its simple concept, clear mechanism, and no need for external energy input. Practice. Among them, the mechanical principle of the tuned mass damper is simple and clear, the change to the original structure is small, and the vibration reduction effect is obvious. It has been maturely used in engineering practice, but it can only have a good performance in a small specific frequency range near the resonance area. Vibration reduction effect, the vibration reduction effect is not good for frequencies that de...
