Driving servo grid damping device for vibration damping control of building structure

Abstract

The invention discloses a driving servo grid damping device for vibration damping control of a building structure. The driving servo grid damping device for the vibration damping control of the building structure comprises a water box, an acceleration sensor and a control system. The water box comprises a box body, N group grid damping units with N group same structures in the box body, the box body are divided into N+1septums by the N group grid damping units, and the adjacent septums are in communication with each other; the grid damping unit comprises an outer frame, grid blade shafts and driving grid blades, the outer frame is longitudinally installed in the box body, a plurality of grille blade shafts are mounted on the outer frame in a vertical mode, the grille blade shafts are arranged at equal intervals in a linear shape, the driving grid blades are fixedly arranged on the grid blade shafts, the box body is also provided with two water box inlet-outlet valves, the two water boxinlet-outlet valves distribute in a diagonal mode, and the control system is correspondingly connected with the water box inlet-outlet valves and the grid blade shafts. According to the driving servogrid damping device for the vibration damping control of the building structure, the damping of the water box can be adjusted, and the energy dissipation and vibration damping function can be achieved.

Description

technical field [0001] The invention relates to the technical field of vibration control, in particular to an active servo grid damping device used for vibration control of building structures. Background technique [0002] In recent years, with the acceleration of urbanization, more and more people are concentrated in cities, and the construction industry market has shown explosive growth, resulting in increasingly tight urban land use. With the promotion and application of new materials, new technologies, and new construction techniques , buildings are developing in the direction of lightness, height and softness, and the development of urban super high-rise buildings has become an inevitable trend. As the height of the structure increases, the span increases and the flexibility increases, resulting in a resonant response of the structure under the action of strong winds, which may affect people's normal production and living vibration comfort requirements, or cause seriou...

Problems solved by technology

[0005] For ordinary TLD, in order to achieve a better vibration reduction effect, it is necessary to install more water tanks in different positions, which takes up more space, costs more, and the vibration reduction effect is relatively limited.

Moreover, the vibration control effect is relatively poor, and its tuning will become very difficult due to strong nonlinearity, and there will be breaking waves under strong excitation, and the proportion of high-order modes participating in the vibration during resonance is relatively large. If it is applied in actual engineering Further precise design is required
