Multi-dimensional collision energy consumption mass pendulum damper

Abstract

The invention discloses a multi-dimensional collision energy consumption mass pendulum damper which consists of a mass ball, a steel cable, a metal cylinder and a viscose elastic material layer, wherein the metal cylinder is an inverted cylinder opening vertically downward; the mass ball, the steel cable and the viscose elastic material layer are all located in the metal cylinder; the mass ball and the steel cable are located in the middle of the metal cylinder; the upper end of the steel cable is fixedly connected with a cylinder bottom plate of the metal cylinder; the lower end of the steel cable is fixedly connected with the mass ball; the mass ball is suspended in the metal cylinder; the viscose elastic material layer is attached to the inner wall of the metal cylinder; and the viscose elastic material layer is arranged in a position capable of enabling collision with the mass ball when the mass ball swings in the metal cylinder so as to realize energy absorption, energy consumption and shock absorption. The damper disclosed by the invention can reduce the vibration reaction of the structure and solve the problem of the structure in seismic resistance and wind resistance.

Description

technical field [0001] The invention relates to the technical field of anti-seismic and wind-resistant engineering structures, in particular to a multi-dimensional collision energy-consuming mass pendulum damper. Background technique [0002] In recent years, structural vibration control has become one of the most popular vibration reduction technologies in the field of engineering anti-seismic and wind resistance. Due to its practicality and effectiveness, it has received more and more attention. [0003] Structural vibration control is usually divided into active control, passive control and hybrid control (that is, a combination of active and passive control). Among them, the damper (also known as the control device), as the core component of the control technology, directly affects the implementation of the control technology. Active control is to use external energy to provide control force to reduce the response of the structure under the action of environmental load...

AI Technical Summary

Problems solved by technology

Active control is to use external energy to provide control force to reduce the response of the structure under the action of environmental loads. Although its control effect is remarkable, it needs to input external energy, and it requires high technical requirements for controller settings, which is expensive and relatively difficult for engineering applications. difficulty
