Abstract

A brand-new integral air disappears antivibration attenuator, belongs to the slanting back guy antivibration area . Its characteristic: It is made up of rain shade, the rubber armor coat, the metal inside hub, the metal outside hub, on the coupling, under the coupling, the aerocyst, the air valve, the barometer, the steel pipe support and so on. The slanting back guy's nuisance vibration transmits through the rubber armor coat and the metal inside hub gives to the aerocyst, the aerocyst take the steel pipe support as the support, provides counter- damping force to affect again in the slanting back guy, thus changed the slanting back guy original vibration modality, realizes restrains the slanting back guy vibration; The attenuator damping force's size may act according to the slanting back guy the vibration characteristic to make the extra wide adjustment, its antivibration effect is remarkable, is suitable specially in each kind of great span diagonal cable bridge takes the slanting back guy the antivibration device, simultaneously it also has the service life to be long, easy to make, the installment, the maintenance and affects and so on.

Description

Technical field [0001] The invention relates to a built-in air energy dissipation and vibration reduction damper installed on the cable-stayed cable of a cable-stayed bridge or the cable of a suspension bridge, and its main function is to effectively reduce the vibration amplitude of the cable-stayed cable in the working state and acceleration. Background technique [0002] Taking the cable-stayed bridge as an example, the cable-stayed cable is an important stressed metal component of the upper box girder of the cable-stayed bridge. The normal service life of the cable-stayed bridge is greatly shortened or accidentally damaged, which will cause huge economic losses and adverse social impacts, so the energy dissipation and vibration reduction technology of cable-stayed cables is the key application technology of cable-stayed bridges. [0003] Stayed cables have been placed in the natural environment for a long time, and they have to withstand the continuous test of sun and r...
