Multi-dimensional dual adjustable damping control device

Abstract

The multi-dimensional double-adjustable damping control device has a structure including a bottom plate, an elastic part I, an elastic part II, a movable part, and a mass pendulum. A support rod is set on the top of the elastic part I, and the deformation of the elastic part I along the Z-axis drives the support rod to move along the Z-axis. Move in the direction of the Z axis to achieve vibration reduction in the Z-axis direction; the elastic part II and the movable part are located above the elastic part I, and the movable part moves in the X-axis direction with the deformation of the elastic part II to achieve vibration reduction in the X-axis direction; The pendulum is arranged at the center of the lower surface of the movable part, and the mass pendulum swings in the Y-axis direction to achieve vibration reduction in the Y-axis direction. Liquid is provided in the mass block of the mass pendulum so that the mass pendulum forms a tuned liquid damper, thereby realizing double vibration reduction. The invention can double reduce the vibration response of the structure under loads such as earthquake or wind in three directions, and has the characteristics of simple principle, convenient installation and high cost performance.

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.
