The utility model is composed of a main cylinder, an auxiliary cylinder, a guide rod, a piston and damping material; the piston which can slide is arranged in the main cylinder, the both ends of the piston are respectively connected with a main guide rod and an auxiliary guide rod, the other end of the main guide rod penetrates through a center hole of a cylinder head to be arranged outside the cylinder head, the auxiliary guide rod protrudes from the main cylinder and penetrates into the auxiliary cylinder, and the piston is provided with a damping hole; the outer circumference of the piston is also provided with a seal ring.
Description
The utility model is a kind of damper that is used for civil engineering antidetonation, vibration damping.
When earthquake takes place, ground motion will cause the vibration of engineering structure, and when being equivalent to the seismic interference of basic intensity, structure promptly may enter the elastoplasticity working state, produces bigger displacement.In addition, the vibration that building or bridge produce under the wind effect is also similar with it, all is the multi-freedom degree low-frequency vibration.How reducing engineering structure and carry dynamic response under the effect at earthquake and wind, is a new research field.Structure energy-eliminating shock-absorbing (shake) system is exactly that some nonload bearing element of bar structure is (as supporting; shear wall; link etc.) be designed to the energy dissipating rod member; or in some position (interlayer space of structure; node; connect seam etc.) the installing energy dissipator; when earthquake or wind occurring and carry; increase along with the structure lateral deformation; energy dissipation component or energy dissipator rate are introduced into inelastic state; produce big damping; a large amount of earthquakes that consume input structures or the wind energy that shakes; make agent structure avoid occurring tangible inelastic state, and the rapidly earthquake of attenuating structure or the wind reaction (displacement of shaking; speed; acceleration etc.) thus protection agent structure and member are exempting from destruction in the shake (or wind) doughtily.
The purpose of this utility model just provides a kind of engineering structure viscous fluid damper that can be used for alleviating the dynamic response of engineering structure under wind and geological process, antivibration (shake) reliability that improves engineering structure, reduction engineering cost.
Engineering structure viscous fluid damper of the present utility model, formed by master cylinder, secondary cylinder, guide rod, piston, damping material, in master cylinder, be provided with the piston that can slide, be connected with leading rod and secondary guide rod respectively at two of piston, the center hole that the other end of leading rod passes cylinder cap is positioned at outside the cylinder cap, secondary guide rod passes master cylinder and pierces into secondary cylinder, also is provided with damping hole on piston.On the excircle of piston, also be provided with seal ring.On damping hole, be provided with the damping screw, on the damping screw, damping hole be set.At the two ends of this damper is that the bottom (or side) of secondary cylinder and the outer end of leading rod are respectively equipped with connecting ring.
Its basic principle is energy-eliminating shock-absorbing rod member or the device as structure, makes guide rod stressed by connection set under the effect of earthquake (or wind), promotes piston motion, makes damping material pass through damping hole, thereby produces damping, reaches the purpose of energy-eliminating shock-absorbing.Be characterized in the earthquake of structure or wind reaction (displacement, speed, the acceleration etc.) sensitivity of shaking, under small reaction, can consume energy, simultaneously, the parameters such as diameter of diameter by changing cavity (master cylinder and secondary cylinder) size, damping hole and damping screw and length, piston can obtain different effectiveness in vibration suppression.
Advantage of the present utility model is that this damper can be used for alleviating the dynamic response of engineering structure under wind and geological process, improves the antivibration reliability of engineering structure, reduces engineering cost, specifically also has the advantage of following aspect:
1. " the engineering structure viscous fluid damper " of institute's model utility has reliable performance, and distortion and the stability of control structure under seismic load and wind action reduces the time deformation of structure under action of long-term load effectively effectively;
2. " the engineering structure viscous fluid damper " of institute's model utility can effectively be controlled structure level vibration and vertical motion;
3. " the engineering structure viscous fluid damper " of institute's model utility can come dissipation energy by the relative movement between piston and the damping material;
4. " the engineering structure viscous fluid damper " of institute's model utility to the earthquake of structure or wind reaction (displacement, speed, the acceleration etc.) sensitivity of shaking, can consume energy under small vibration;
5. measure by dynamic experiment, " engineering structure viscous fluid damper " power and the displacement hysteresis loop of institute's model utility are a full ellipse, have extremely strong energy dissipation capacity;
6. " the engineering structure viscous fluid damper " of institute's model utility can be widely used in the strengthening reconstruction of antidetonation, vibration damping and the old engineering of building structure, tall and slender structure, towering pylon, bridge, flexible pipe, pipeline engineerings such as (lifeline engineering);
" engineering structure viscous fluid damper " simple structure of institute's model utility, power transmission is clear and definite, mechanism is clear, cheap, be convenient to produce and apply.
