Self-powered self-adaptive eddy current tuned mass damper

Abstract

The invention relates to a self-powered self-adaptive eddy current tuned mass damper. The self-powered self-adaptive eddy current tuned mass damper is composed of a fixed mass block, a variable mass block, a permanent magnet rod, an electromagnetic slot, a conductor plate, a spring, an adjustable mass device, an energy collection unit and a monitoring driving unit, wherein the bottom end of the spring is connected with the top of the adjustable mass device, and the top end of the spring is connected with the bottom of the fixed mass block; the variable mass block is fixedly arranged at the top of the fixed mass block; and the center of the variable mass block and the center of the fixed mass block are each provided with a permanent magnet rod channel. The mass of the variable mass block is adjustable, and thus accurate control of the frequency of the tuned mass damper is achieved. The energy collection unit recovers eddy current in the conductor plate and then supplies the current to the monitoring driving unit. Compared with the prior art, accurate adjustment of the frequency of the tuned mass damper can be achieved, the damping effect is improved, the design of the damper is simplified, the damper is good in control effect, outside power is not needed, and the damper is simple in structure, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a self-powered adaptive eddy current tuning mass damper. Background technique [0002] In today's society, tuned mass dampers have attracted widespread attention because of their advantages of small changes to the original building structure, convenient construction, and significant vibration reduction control effects, and have been used in domestic and foreign building structures, such as Taipei 101 Building, Shanghai Center etc. However, the traditional tuning mass damper has the disadvantage of tuning sensitivity to frequency. Not only the damage of the building structure itself will affect the vibration reduction effect of the tuning mass damper, but also its own characteristics, such as the degradation of the viscous damper. , the corrosion of the spring or the change of the mass when a certain component of the building structure acts as the mass of the tuned mass...
