Device.
Background technology
Earthquake is one of main harm for threatening engineering structure safety, and in earthquake, the structure of building can be damaged,
Phenomenon of caving in can be generated under serious conditions.Energy-eliminating shock-absorbing technology is as a kind of passive structural vibration reduction control technology, in recent years
Through being widely applied among building, energy-eliminating shock-absorbing device is added in the energy-eliminating shock-absorbing technological reality structure, it is additional to subtract
The effect of device and building structure shared earthquake itself is shaken, acts on reducing knot by the energy consumption of additional vibration absorber
The dynamic response of structure in itself, ensure that the security of building.At present on the market there are many energy-eliminating shock-absorbing devices, such as adjust
Humorous mass damper, Tuned Liquid are sticked damper and frcition damper etc., and fluid linking damper refers to by glutinous
Stagnant liquid flows generation damping to consume vibrational energy, in fluid linking damper of the prior art in piston hole or gap
Viscous damping power cannot all be adjusted, and the damping effect for so resulting in engineering structure is bad, greatly limits viscous damper
Use scope, can not widely apply fluid linking damper.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of simple in structure, viscous damping power to be adjusted, and
And the viscous mass damper of tuning that damping effect is good.
The utility model is the technical scheme adopted is that tune viscous mass damper, including the first cylinder barrel, described first
Cylinder barrel includes the first left end cap and the first right end cap, and support base, the support are installed on the inside of first right end cap
The other end of seat is fixedly connected with the second cylinder barrel, and the horizontal axis of first cylinder barrel and the second cylinder barrel coincides, and described second
Cylinder barrel includes the second left end cap and the second right end cap, and the viscous mass damper of tuning further includes first piston body, the 3rd
Piston only and through the second piston for both passing through the first left end cap and the second left end cap and extending into inside the second cylinder barrel
Body, the first piston body and the 3rd piston only both pass through the first right end cap and extend into the first cylinder barrel, and described
One piston only and the 3rd piston only are symmetrical in horizontal axis, and the first resistance is offered on the second left end cap of second cylinder barrel
Buddhist nun hole offers the second damping hole on second right end cap.
The beneficial effects of the utility model are：The structure of the viscous mass damper of the tuning, when being subject in both direction
Extruding force when, the first cylinder barrel of damper and the volume of the viscose liquids in the second cylinder barrel can be adjusted at this time, when
Two piston onlies towards the second right end cap direction movement when, the viscose liquids in the second cylinder barrel can be from the second damping hole at this time
In enter in the first cylinder barrel, first piston body and the 3rd piston only are also moved towards the first left end cap direction at this time, the
Viscose liquids in one cylinder barrel will enter in the second cylinder barrel from the first damping hole so that in the first cylinder barrel and the second cylinder barrel
Viscose liquids can flexibly flow, such viscous damping power can also be adjusted flexibly, so as to so that the damper
Structure can be neatly applied in many building occasions, and the damping effect that the structure is brought is good.
As priority, the second piston body includes second piston and the second guide rod being connected with second piston, institute
It states and threeth damping hole symmetrical on the second guide rod is offered in second piston, using this structure, from the first damping hole
The viscose liquids being flowed into the second cylinder barrel can enter the lower area of the second cylinder barrel along the 3rd damping hole.
As priority, the first piston body and the 3rd piston only include first piston and connect with first piston
The first guide rod connect offers fourth damping hole symmetrical on the first guide rod on the first piston, using this knot
Structure, the interior viscose liquids in first piston lower part of the first cylinder barrel will enter upper in the first cylinder barrel from the 4th damping hole
Portion region, then the viscose liquids of the upper area in the first cylinder barrel enter again in the second cylinder barrel, can thus make first
Viscose liquids in cylinder barrel and the second cylinder barrel form a reflux, improve the viscous damping power for tuning viscous mass damper,
Damping effect is more preferable.
