Abstract
A device for improving the damping effect of a viscous damper in the vertical direction comprises a barrel body outer shell containing damping fluid, and a low connecting board which is installed at the lower portion of the barrel body outer shell. A hollow plunger is arranged inside the barrel body outer shell. The upper portion of the hollow plunger is fixedly connected with an upper connecting board which is provided with an air outlet hole. A damping board is fixed in the hollow plunger. A damping through hole is formed in the center of the damping board. According to the device, the damping board is arranged, the damping through hole is formed in the center of the damping board, the damping coefficient in the vertical direction is adjusted through the size of the center damping through hole, the damping coefficient in the vertical direction can also be adjusted when environment temperature changes, and the optimal damping effect can be achieved.
Description
Technical field
The utility model relates to a kind of vibration damping equipment, particularly a kind of device of the damper Vertical direction effectiveness in vibration suppression of tackifying.
Background technique
Existing Viscodamper damper is comprised of the cylinder shell that holds damp liquid, lower connecting plate (casing cylinder and lower connecting plate welding), hollow plunger and upper junction plate.Hollow plunger is immersed in the damp liquid, and damp liquid produces damping force to hollow plunger level, movement in vertical direction, thereby reaches the purpose that reduces object vibration.
Existing Viscodamper damper is that damp liquid reaches effectiveness in vibration suppression to the damping force of its generation during by the hollow plunger motion, because long-pending to meet liquid level much larger than Vertical direction long-pending for the liquid level of meeting of plunger horizontal motion, and form effect also is that substantially horizontal is greater than the damping force of Vertical direction, therefore the Vertical direction effectiveness in vibration suppression is relatively poor, existing damper Vertical direction damping constant approximately is 0.4～0.9 times of substantially horizontal, and the damper principle that the RHY type test data of the Viscodamper of GERB company damper sees Table other damp liquid formation of 1(is identical).Viscous damping coefficient is relevant with shape, the size of object.

Summary of the invention
The purpose of this utility model is to provide a kind of can increase the Vertical direction damping constant, improves the device of Vertical direction effectiveness in vibration suppression.
For achieving the above object, the technical solution adopted in the utility model is: the cylinder shell that is contained with damp liquid in comprising, and the lower connecting plate that is installed in the cylinder shell bottom, in cylinder shell, be provided with hollow plunger, hollow plunger top is fixedly connected with the upper junction plate that offers air outlet hole, be fixed with damping plate in the described hollow plunger, and offer the damping through hole at the center of damping plate, in order to the damping constant according to ambient temperature and vibration damping requirement adjustment Vertical direction.
The diameter of described damping through hole and the diameter ratio of damping plate are d/D=0.25～0.75.
Be positioned at the manhole that also evenly to offer eight diameters on the circumference in the damping through hole outside be 10～15mm on the described damping plate.
Described damping plate is apart from the distance h of hollow plunger lower end mouth=10～30mm.
The utility model arranges damping plate and offers the damping through hole at the damping plate center, and the size of center damping through hole is to adjust the damping constant of Vertical direction, and the also damping constant of this direction of capable of regulating when variation of ambient temperature obtains best effectiveness in vibration suppression.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
Referring to Fig. 1, the utility model comprises and is contained with damp liquid 7 in the cylinder shell 5, and the lower connecting plate 6 that is installed in cylinder shell 5 bottoms, in cylinder shell 5, being provided with hollow plunger 1, hollow plunger 1 top is fixedly connected with the upper junction plate 2 that offers air outlet hole 4;
Referring to Fig. 2,3,4, the utility model damping plate 8 is fixedly connected with hollow plunger 1 inwall, damping plate 8 is apart from the distance h of hollow plunger 1 lower end mouth=10～30mm, offer damping through hole 9 at the center of damping plate 8, the diameter ratio of the diameter of damping through hole 9 and damping plate 8 is d/D=0.25～0.75, and is positioned at the manhole 10 that also evenly to offer eight diameters on the circumference in damping through hole 9 outsides be 10～15mm on the damping plate 8.
The utility model arranges damping plate 8 and offers damping through hole 9 at damping plate 8 centers, be positioned on the damping plate 8 on the circumference in damping through hole 9 outsides and offer manhole 10, the size of center damping through hole 9 is to adjust the damping constant of Vertical direction, when variation of ambient temperature is the also damping constant of this direction of capable of regulating, obtain best effectiveness in vibration suppression; Circumference can make damp liquid better by damping plate 8 by 10, prevents from forming air bubble in the damp liquid, affects damping characteristic.
Object in viscous liquid (less than 0.2m/s) damping force F during low-speed motion=-cv.Viscous damping coefficient c is relevant with the character of shape, size and the medium of object.Meet the damping constant of the identical flat board of liquid level area of contour in the damp liquid greater than cylindrical damping constant.Therefore, design as required the area of damping plate 8, suitably improve the Vertical direction damping constant.Can make be up to the standard 0.9～1.5 times of direction of Vertical direction damping constant by adjusting damping plate aperture ratio d/D.
