Description
Technical field
The present invention relates to a kind of vibration control apparatus, a kind of damper, especially building structure stretch the viscid resistance of closed type
Buddhist nun's device.
Background technique
Damper is a kind of widely used vibration control primary element, for machinery, the vehicles, bridge, building knot
The vibration damping of structure, buffering, energy consumption.Common damper is hydraulic oil cylinder type, and piston, only in axial mutually movement, claims relative to oil cylinder
For uniaxial damper, be made of kinetoplast, kinetoplast bar, cylinder body and sealing, kinetoplast is generally pylindrical, and kinetoplast is equipped with several small
Hole or between cylinder body there are appropriate radial clearance, oil cylinder is divided into two kinetoplast chambers by kinetoplast, and kinetoplast is intracavitary filled with hydraulic oil or viscous
Spend slightly higher viscous liquid, such as silicone oil, when kinetoplast is relative to cylinder movement, be enclosed within compression side move endoceliac liquid by
It squeezes, pressure rise, driven body space or aperture flow to another kinetoplast chamber, and two kinetoplast cavity pressure differences form the movement to kinetoplast and hinder
Power, acting, converts thermal energy for mechanical energy, to achieve the purpose that absorb outside energy, therefore can be widely applied to damping, delays
The occasion of punching, energy consumption, such as vehicle suspension system and building energy-dissipating and shock-absorbing.
Damper is continuously improved by decades, very perfect.But due to constructing aspect, there is born lack
It falls into：1) strict sealing must be used, but sealing element is prone to wear or aging, once seal failure, pressure difference can not be established, resistance
Damping properties will be lost rapidly；2) design of part is complicated, quantity is more, requirement on machining accuracy is high, therefore cost is high；3) damping liquid
It is instantaneous heating up higher locally by high shear when passing through orifice restriction, it is easy aging under long term, damper is caused to lose
Effect；4) sediment and wear particle object influence damping parameter in damping liquid, and damper is accelerated to destroy；Due to above,
The damper of this form, other than the best brand of product of high quality, the universal service life is lower, and maintenance cost is high.
Now common Large Span Bridges are sealed into rubber friction type sealing element, damper permanent worker with cable fluid linking damper
Contacting friction in work between piston and rubber seal will cause sealing part abrasion, lead to seal fails, and damper leakage occurs
Liquid and can not effective vibration damping, cause damper service life not grown, can also make wear-out part replacement difficult, maintenance cost height etc. is no
Foot.
