A three-way shock-absorbing mass-tuned damper

Abstract

The invention relates to a three-direction shock absorption mass tuning damper. A steel cylinder is internally provided with a horizontal shock absorption device. The horizontal shock absorption device is connected with the inner wall of the steel cylinder through horizontal adhesion dampers and horizontal springs. The center of the horizontal shock absorption device is provided with a vertical mass block. The bottom of the vertical mass block is connected with a base through a vertical adhesion damper and vertical springs. An oriented rotating shaft support is arranged between the base and the vertical adhesion damper. The oriented rotating shaft support is connected with the vertical adhesion damper through an oriented rotating shaft. The composite type mass tuning damper capable of playing the horizontal shock absorption function and capable of playing the vertical shock absorption function is formed, the three-direction function in the transverse direction, the longitudinal direction and the vertical direction is achieved, and the three-direction shock absorption mass tuning damper has the advantages of being simple in design, easy to mount, adjustable in base frequency and mass, stable in damping effect and the like and has wider application compared with a general mass tuning damper.

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of civil engineering structures, and in particular relates to a three-way shock-absorbing mass tuned damper for controlling the vibration of a building and reducing the structural response of the structure under the action of wind load and earthquake load. Background technique [0002] For high-rise and long-span structures, the control of lateral deformation of structures under wind loads and earthquake loads has received extensive attention and attention. It has been proved by a lot of practice that the mass tuned damper is a very effective vibration reduction control device. It can be installed in a suitable position of the structure, and through reasonable setting of product static stiffness, mass block and damping parameters, it can greatly reduce the The lateral vibration displacement amplitude of the structure, and correspondingly reduce the horizontal shear ...

AI Technical Summary

Problems solved by technology

[0003] When controlling the vibration of general long-span structures, such as pedestrian bridges and corridors between buildings, the conventional solution is to use a vertical mass-tuned damper to control the vertical vibration of the structure, and use a vibration-isolation support that can be equipped with a viscous damper to control the longitudinal vibration. , such an approach is expensive, cumbersome to design, and complicated to install

For towering structures with large-span components, there are both horizontal shock absorption requirements and vertical local component shock absorption requirements. When the mass-tuned damper shock absorption scheme is used, it is necessary to control horizontal vibration and control vertical vibration respectively. Two systems, also accompanied by a significant increase in cost, troublesome design and complicated installation

[0004] In addition, for the mass-tuned damper with horizontal shock absorption, the mass requirements in the two directions are usually not completely consistent. The traditional mass-tuned damper mass is constant in the X and Y directions and cannot be adjusted. There is room for improvement.
