Problems solved by technology

However, frictional energy consumption often occurs when the case is stuck and does not work, and the viscous damper must have enough space. Excessive space often increases the local windward area of ​​the self-supporting towering structure, and is not conducive to installation.

Abstract

The invention relates to an integrated pore energy-dissipating annular tuned mass damper, which is composed of an outer stiffening plate, a TMD shell, an adjustable spring, a mass piston, a viscous fluid, a partition, a sealing sliding plate, and an inner stiffening beam. The tuned mass damper is tightly connected to the structure through the TMD shell, the adjustable spring is connected to the mass piston and the TMD shell through a horizontally hinged spring node, the inner / outer sliding plates of the sealed sliding plate can slide each other, and the cavity is filled with viscose Viscous fluid; the mass piston provides the mass, the adjustable spring provides the stiffness, and the inertia force causes the mass piston to slide, so that the viscous fluid flows through the damping hole to produce the required damping. The invention has the advantages of simple structure, small volume, good durability, stable and efficient damping output and the like.

Description

technical field [0001] The invention belongs to the technical field of vibration control devices for civil engineering structures, and relates to an integrated pore energy-dissipating ring-shaped tuned mass damper for self-supporting towering structures. Background technique [0002] Self-supporting high-rise structures are widely used in social production and life. With the continuous development of the national economy, wind power towers, self-supporting transmission line towers, high-rise chimneys and other structures are gradually increasing, and they are increasingly developing in the direction of high and soft. Since the cross-section is often circular or nearly circular polygon, the slender structure makes them very prone to vortex induced resonance, so that they are in the working state of reciprocating stress for a long time, so that when the ultimate load is not reached, the Destruction due to fatigue damage is very likely to occur, causing great economic losses. ...
