Description
Technical field
The present invention relates to field of civil engineering, particularly relate to a kind of three-way vibration control method and three-way vibration controller of works, it is mainly used in the vibration isolation of long-span beams in building construction and the bridge engineering.
Background technology
In 20th century, world's bridge engineering is obtained great achievement, and the long span bridge beam is born like the mushrooms after rain.As be communicated with the Japanese alum bridge (suspension bridge) of Honshu one four countries, single span 1990m; The profit of China Jiang Daqiao (suspension bridge) that makes the best use of the advantages, span 1490m.The striding greatly of bridge, lightweight and flexible trend are more and more surging, and a difficult problem such as stability enlarges markedly but the Structure Safety for Bridge, the wind that produce shake thereupon.
Enter 21 century, world's bridge engineering will enter the bridge construction new period on island over strait.The emergence of Bridges in Our Country engineering, attract attention in the whole world, and its construction level of large-span suspension bridge and cable stayed bridge leaps to world's rank of advanced units.China is organizational planning's engineering over strait energetically, as the lonely foreign passage of the mouth of the Zhujiang River, and connection island, Zhoushan engineering.Xiang Haifan academician estimates " China of 21 century will make brilliant achievement in bridge construction, stand erect in the row of world's bridge power " (seeing document [1]).
The development of bridge construction needs the basis of developing into the bridge theory.So the shake research of the transformation of theory, computational fluid dynamics theory, aerodynamic parameter identification and the wind resistance measure aspects such as (as the bridge vibration control measure) that super large is striden bridge of bridge wind shows important especially.
In fact, Chinese scholars has been made number of research projects with regard to bridge vibration theory and bridge vibration control.
1972, Yao Haoping (J.T.P.Yao) professor proposed " structure control " theory first, thereby had started the new period of structure control research.Structure control divides three parts: architectural characteristic from the self diagnosis of perception, structure functional performance, the automatic control of structural response.
The self diagnosis from perception and structural performance of architectural characteristic is the automatic monitoring and the automatic diagnosis of architectural characteristic.For this reason, Europe is advanced people such as duckweed academician Heilungkiang Hulanhe River bridge is adopted the fiber optical grating intelligent monitoring technology
[2]And people such as professor Li Hui adopts integrated technology that large bridge is carried out intelligent health monitoring
[3]These monitoring technology show special efficacy greatly to performances such as the strain of monitoring bridge rapidly and accurately, temperature deformations, and Gernral Check-up provides reliable basis to bridge.
The course in existing more than 30 year of automatic control research of structural response.Gu Mingjiao awards etc. the vibration of long span bridge beam and buffets control
[4]Make good summary, and adopted the flutter of measure control bridge, buffetings such as aerodynamics measure and mechanical damping device respectively, and proposed the notion of " buffeting type selecting ".Document [5] by numerical method and evidence tuned mass damper, TMD (Tuned Mass Dampers, be called for short TMD) improve the validity of bridge critical wind speed of flutter.Document [6] swashs resonance with TMD control bridge whirlpool, releases TMD optimized parameter formula, and prove by example: TMD makes the displacement of bridge vortex-induced vibration reduce 46%.The structure of TMD is as shown in Figure 5: be made up of a mass 6, spring 7, damping 8 and some rollers 9 (steel ball or laminated rubber etc.); The system of 4 kinds of object structures is connected on the works 10 thus.And produce relative displacement, speed between works, thereby produce spring force and damping force, these two kinds of power can reduce the partial action of wind or earthquake.This equipment is used in states such as the U.S., Japan, New Zealand.The greatest drawback of TMD is the problem that only can reduce from a certain one-side for example unidirectional or direction vibration.
Document [7,8,9] adopts multiple TMD, and ((Multi-Tuned Mass Dampers is called for short MTMD later on) and lever TMD buffet control to raising the Pu bridge.So-called multiple TMD is a plurality of TMD; So-called lever TMD promptly adds rigid rod in TMD, this can overcome traditional suspension TMD big shortcoming that takes up room, its more convenient being installed in the inadequate spaces such as case beam, designed 7 kinds of TMD systems of corresponding different quality ratio in the literary composition, studies show that: the MTMD system is better than the control effect of single TMD system.
More than research has mainly reflected the progress of controller such as TMD, MTMD and control theory thereof, but can not solve for example three direction vibration isolations of bridge of multi-functional control works, about so-called three directions are meant, about and torsional direction.
Summary of the invention
