Description
Technical field
The present invention relates to a kind of Spiralism type viscous damper, more particularly to a kind of viscous resistance of Spiralism type for assembling amplifying device
Buddhist nun's device, combines the advantage of viscous damper and gear driven type displacement/speed amplifying device, effectively increases damper damping
Effect.Belong to civil structure（Including skyscraper, tall and slender structure etc.）Vibration control field.
Background technology
In recent years, the passive control technology such as base isolation, energy-dissipating and shock-absorbing and tuned mass damping control because its concept is simple,
Clear mechanism, cost are relatively low, damping effect is notable and are at home and abroad used widely in civil engineering.Wherein, viscous damping
Device is good with its good economy performance, applicability, the low advantage of maintenance cost, receives the attention of vast civil engineering researcher.
Common viscous damper be hydraulic jack hole formula damper, by sleeve, piston, oil sealing, damping hole, guide rod and
Viscous fluid etc. is constituted.The mechanism of action is when piston makees axially reciprocating in cylinder barrel, due to the pressure official post before and after piston
Decelerating effect of the viscous fluid from grease chamber through throttle orifice produces viscous damping force acting, and mechanical energy is converted into heat energy, so that
The purpose for absorbing outside energy is reached, therefore can be widely applied to damping, buffering, the occasion of power consumption..
But current viscous damper still suffers from certain deficiency：（1）The viscous damper of early stage is usually single rod
Form, as the piston moves, because the volume of actual upper cylinder internal viscosity fluid is compressible material so that when piston rod is extracted out
When, this partial piston bar being extracted volume occupied in oil cylinder, which can not be instantly obtained in compensation, oil cylinder, can produce vacuum
Phenomenon, prevents piston rod from continuing motion;When piston rod bounces back, entered originally in the viscous fluid part of another side cylinder of piston
Enter in oil cylinder, and the volume of oil cylinder does not increase, so as to cause dieback phenomenon；（2）Learnt by experiment, damper is in small stroke bar
The damping force of part bottombearing damper does not reach the performance provided by damper theoretical formula, it is impossible to reach the very little position under geological process
The very high damping ratio as obtained by theoretical formula method is provided during shifting, existing clearly has similar display bullet of being connected with spring
The phenomenon of spring insufficient rigidity, it is impossible to show the mechanical behavior of pure viscosity.Therefore, changed on the basis of existing viscous damper
Enter, using the outer STH Spiralism type viscous damper of connection gear driven type amplifying device, dieback phenomenon can be eliminated and one
Determine displacement enlargement in degree and improve damping ratio, this is significant for the shockproof control of Practical Project.
The content of the invention
Vacuum phenomenon and dieback phenomenon in oil cylinder caused by piston rod piece in order to solve viscous damper, amplify simultaneously
Damper and the wherein relative displacement of liquid and relative velocity, purpose proposed by the present invention are that a kind of Spiralism type of offer is viscous
Damper, the device is used as damping on the basis of the advantage of traditional viscous damper is played by the use of the drive connection between gear
The triggering device of device, and displacement and the speed of vibration of building are exaggerated simultaneously, based on the mechanism of action of traditional viscous damper,
Increase power consumption, reaches more preferable effectiveness in vibration suppression.Under the effect such as wind or/and earthquake, pass through the relative of gear drive basis/floor
Displacement, using the radius ratio between travelling gear and rotating vane, is amplified to displacement of the lines on the outside of damper casing Leaf,
Box house viscous fluid is forced in a short time with larger flow velocity by opening, so as to produce larger damping force, increases
Plus the effect of oscillation damping and energy dissipating.
