Description
Technical field
The present invention relates to structural damping technical field, especially a kind of pressure controllable type fluid linking damper.
Background technology
In recent years, violent earthquake takes place frequently, and the destructiveness of own has seriously threatened the life of the mankind with the secondary disaster caused
It deposits and develops.Meanwhile being increased substantially as national economy is horizontal, building trade department of China is to house architectural structure antidetonation
The requirement of performance is also higher and higher.Fluid linking damper can effectively mitigate the earthquake response of structure, viscid when coming earthquake
Characteristic causes the increase of structural damping, damper to consume most of energy, protect main structure.
Fluid linking damper is flowed in damping hole by resisting medium to generate Damping work vibrational energy, is a kind of nothing
Rigidity, the energy consumer of velocity correlation type.Fluid linking damper can effectively mitigate the earthquake response of structure, when coming earthquake,
Viscid characteristic causes the increase of structural damping, damper to consume most of energy, protect main structure.The base of fluid linking damper
This formula is F=CVα, wherein F expression damping forces, C is damped coefficient, and V indicates the speed of piston motion, and α is Rate Index.From
Formula can be seen that fluid linking damper and belong to velocity profile damper, and Rate Index directly influences the energy-dissipating property of damper.
The resisting medium of traditional fluid linking damper riddles in master cylinder, and when piston quickly moves, the master cylinder chamber of piston both sides will produce
Raw pressure difference, resisting medium still riddle the master of piston both sides by the damping hole jet flow that is arranged on piston, resisting medium
In cylinder chamber.The damping force that resisting medium is generated by the damping hole jet flow being arranged on piston, can quickly reduce vibration width
Degree consumes inputted vibration energy.Although the master cylinder chamber of piston both sides should have pressure difference, it could realize fluid injection and then consume
Earthquake or wind-induced vibrational energy, but excessive pressure difference can not only generate the dynamic stiffness of damper, and dynamic stiffness may draw
The abnormal Internal Force Redistribution of structure is played, and then destruction may be generated to the sealing system and cylinder barrel side wall of damper.And
Speed quickly when can even lock, when fluid linking damper by it is locked when, or even fluid linking damper detonation can be caused, or cause to live
Stopper rod is bent or piston rod inclination is stuck, finally fluid linking damper is caused to destroy.
Chinese utility model patent CN 203,670,585 U discloses a kind of viscid resistance of new and effective three-dimensional
Buddhist nun's device, structure include oil cylinder, damping structure and damper rod, and damper rod one end is fixed on upper cover plate, and the other end is tied with damping
Structure is connected, and upper cover plate is connected to by elastic sealing bands on cylinder side wall, one end and damping that damper rod is connect with damping structure
The surface of structure offers energy consumption hole.This, which is designed, produces the effect of Efficient Damping, but for cylinder interior pressure it is excessive this
Aspect does not make effective measures, therefore in prolonged cylinder interior pressure is excessive, it is possible that cylinder body was destroyed
Situation, thus the device structure and design on there are prodigious defects, the needs of modern production can not be met.
Chinese utility model patent CN 206,448,396 U discloses a kind of intelligent fluid linking damper, the viscous damping
Device can pass through the opening and closing of solenoid valve control damping hole under different speed or acceleration.This design can adjust viscous damping
The damping of device improves the effect of energy-dissipating and shock-absorbing, improves safety and the durability of structure.In order to improve the damping of fluid linking damper
Effect, the damping hole on piston is very little.When piston generates movement, sticky resisting medium generates consumption by damping hole
Can, if damping hole is too greatly, it will lose effective energy consumption effect.In addition, similarly, the quantity of the damping hole on piston is not
Can be too many, because damping hole number excessively can equally weaken the effect of damping energy dissipation.Therefore with magnetic valve control part damping hole
It is turned on and off, inevitably, solenoid valve can be made to open and close front and back resisting medium passage section variation huge.So in viscid resistance
When Buddhist nun's device both ends generate relative motion, great variety occurs for hydrodynamic performance, to make the relevant parameter of fluid linking damper
C, α generate great changes, and consequence caused in this way is the fluid linking damper computation model chosen when being calculated with house architectural structure
Widely different, even if being analyzed by refining, front and back totally different mechanics parameter variation may result in unpredictable internal force weight
Distribution, or even cause the dangerous of structure.In addition, being turned on and off by solenoid valve control damping hole, can not play and subtract
The effect of pressure value in small two master cylinders can not play the effect of the safety of protection cylinder body and sealing system.
Invention content

Pipe connects (as shown in Figure 2) by bolt seal, therefore when solenoid valve is opened, left master cylinder and right master cylinder can by fluid-through tube and
Solenoid valve is connected to, and can generate the circulation of resisting medium.Pressure sensor is by pressure-sensing device, conversion element, translation circuit
It is constituted with accessory power supply, is bolted on master cylinder casing wall (as shown in Figure 3), it acts as two master cylinder internal viscosities of record
The pressure value of resisting medium, and real-time Transmission is to controller.Controller is to control the main of solenoid valve keying to enable device, by leading
Line is separately connected pressure sensor, it acts as real-time reception pressure sensor transmission pressure value, and with preset regulating valve
Value is compared, when pressure value, which is more than, adjusts threshold values, by the unlatching of polygon control survey solenoid valve, when pressure value is less than regulating valve
When value, pass through the closing of polygon control survey solenoid valve.The power supply system that the present invention uses is storage battery power supply system, power supply system point
Solenoid valve, controller and pressure sensor are not connected, and power supply is provided for it.Controller is positioned over dampener body with power supply system
(as shown in Figure 1) outside.Limiter is welded by way of annular solder with master cylinder inner wall, and its role is to prevent piston section from hindering
Open close liquid pipe.
With the above structure, when viscid fluid damper is when both ends generate relative motion, piston generates in cylinder body
Corresponding to move back and forth, the pressure value in master cylinder is input to controller by the pressure sensor of side in real time on piston.Control
Device judges whether pressure reaches preset adjusting threshold values in real time.Threshold values is adjusted according to master cylinder and sealing element intensity and considers safety
Coefficient and be arranged.The adjusting threshold values should ensure that the safety of the master cylinder under larger earthquake or wind shake effect, and ensureing will not be to close
Envelope system generates destruction.In addition, the adjusting threshold values can not be too small, to ensure that damper keeps efficient energy consumption effect, value
Generally set 25~50Mpa.Controller is judged by the pressure value that pressure sensor exports in real time, when the pressure value is more than
When adjusting threshold values, sends out the unlatching of control instruction control solenoid valve and then controlled when pressure value is no more than adjusting threshold values
Solenoid valve is closed.When solenoid valve is opened, the resisting medium in master cylinder in left and right master cylinder can be circulated by fluid-through tube.Due to damping
Some master cylinder therein is always compressed in the movement of device piston rod, and another master cylinder volume becomes larger therewith, therefore volume compression
The pressure of master cylinder internal damping medium may constantly increase during exercise, or even threaten damper itself under certain extreme situations
Safety, and the pressure change for another master cylinder that volume becomes larger therewith is opposite, in some instances it may even be possible to become negative pressure.Two masters
Because solenoid valve is opened liquid communication by fluid-through tube occurs for the resisting medium of cylinder, can play and be reduced rapidly liquid pressure in master cylinder
Strong effect.In order not to allow the key parameter C and α of damper to be greatly affected, it is necessary to assure this resisting medium circulation
Quickly occur, to not influence the fluid injection mechanism that piston rod goes out damping hole.Therefore the area of section of fluid-through tube is set as damping
More than the three times of hole area of section, make left master cylinder and the pressure immediate stability in right master cylinder, risk factor is reduced, in addition, this resistance
Buddhist nun's device is simple in structure, can carry out pressure adjusting, and each parts and accessory can be prefabricated in the factory processing, economical rationality.Using this
Kind pressure controllable type fluid linking damper can guarantee that its hysteresis loop is stablized, the better protecting effect of damping, safety coefficient higher, knot
Structure durability is high, can be used for a long time.
