Multidirectional rolling type vibration absorption damper

Abstract

The invention discloses a multidirectional rolling type vibration absorption damper which comprises a metal inner box body and an outer box body which are installed together in a sleeving manner; the outer wall of the inner box body is connected with the inner wall of the outer box body through vertical guide rails; the bottom of the inner box body is fixedly connected with the outer box body through an elastic vibration absorption component; the inner wall of the inner box body is connected with the outer wall of a mass block through shape memory alloy energy dissipation springs; a plurality of metal balls which can roll are arranged in the inner box body and are arranged in spherical grooves of the inner box body; the mass block is arranged on the tops of the metal balls, is contacted and connected with the metal balls, can slide in the inner box body in an arbitrary direction and enables the shape memory alloy energy dissipation springs to deform, so that the mass block has the action of energy dissipation vibration absorption in the horizontal direction; and energy in the vertical direction is dissipated by sliding up and down of the inner box body, and thus the multidirectional energy dissipation vibration absorption action is exerted.

Description

technical field [0001] The invention belongs to the field of vibration reduction control of large-span space structures, and in particular relates to a multi-directional rolling type vibration reduction damper. Background technique [0002] In recent years, with the advancement of science and technology and the development of construction technology, the construction industry has entered a stage of rapid development, and the building structure is developing in the direction of flexibility and towering. Due to the complexity of its structural form, the towering building structure has a strong structural dynamic response under the action of earthquake or wind load. How to reduce the dynamic response of buildings and make buildings meet the basic requirements of safety and beauty has attracted more and more attention. [0003] Traditional seismic structural systems actually rely on the damage of structures and load-bearing components to consume most of the input energy. This m...

Problems solved by technology

[0005] At present, the common vibration control devices can only control the vibration in a certain direction or in a few specific directions. Considering the multi-dimensionality of the direction of earthquake or wind load and the complexity of structural vibration, such a vibration control device cannot be very good. meet the requirements of vibration control
