Multidimensional adjustable double damping control device

Abstract

A multidimensional adjustable double damping control device structurally comprises a base plate, an elastic part I, an elastic part II, a movable part and a mass pendulum, wherein a support rod is arranged at the top of the elastic part I, the elastic part I can deform in the Z axis direction to drive the support rod to move in the Z axis direction, so that damping in the Z axis direction is realized; the elastic part II and the movable part are located above the elastic part I, and the elastic part moves in the X axis direction with the deformation of the elastic part II so that damping in the X axis direction is realized; the mass pendulum is arranged at the center part of the lower surface of the movable part and swings in the Y axis so that damping in the Y direction is realized. A liquid is arranged in a mass block of the mass pendulum so that the mass pendulum forms a tuned liquid damper, and accordingly, double damping is realized. According to the multidimensional adjustable double damping control device, shaking of the structure in three directions or vibration response under load effects of wind and the like can be double reduced, and the multidimensional adjustable double damping control device has the advantages that the principle is simple, installation is convenient, the cost performance is high and the like.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a multi-dimensional double-adjustable damping control device, which is mainly used in the damping control of large-span, towering and other related structures. Background technique [0002] In recent years, in the case of more and more serious losses caused by large earthquakes and wind disasters, people are increasingly aware of the limitations and inalterability of traditional structural design for natural disasters of unknown intensity (such as the different seismic fortification intensity). Deterministic and disastrous weather exceeds historical statistics, etc.). Structural vibration control technology has changed the traditional way of using load-bearing structural systems to directly resist disasters, and uses non-load-bearing structural control devices or components to reduce the disaster response of the main structure and improve the ability of engineering structures t...

Problems solved by technology

[0007] At present, more and more vibration damping devices are used in practical projects, such as: Taipei 101 Building, Shanghai World Financial Building, etc., but most of the various forms of vibration dampers only control vibration in one or two directions of the structure. However, considering the complexity of structural vibration, such a vibration control device cannot well meet the requirements of vibration control.
