Description
Technical field
The present invention proposes a kind of " not having the rotating fluid of leakage damper ", belongs to field of vibration control.
Background technique
Fluid damper is a kind of effective structural damping device, but in the fluid damper working procedure, exists the possibility of fluid damper inner fluid seepage, and therefore in the occasion that does not allow leakage, the use of fluid damper just is restricted.The present invention proposes a kind of fluid damper, and this damper does not use Sealing, thereby is difficult for taking place the leakage fault.
Summary of the invention
Technical problem:The objective of the invention is a kind of through proposing " not having the rotating fluid of leakage damper ", be specially adapted to not allow the structural vibration control under the leakage condition.
Technological scheme:For solving the problems of the technologies described above, technological scheme provided by the invention is:
The present invention does not have leakage rotating fluid damper and utilizes the blade movement power consumption in the contactless promotion damper of magnetic force, plays the effect of control vibration.
This nothing is leaked rotating fluid damper and is comprised: disc flange on the upper end that disk, the lower disk flange that is oppositely arranged with disk, with the cylinder that disk and lower disk flange do not have oil hydraulic cylinder that leakage is connected, upper end with opening has disc flange, upper end have a cylinder of disc flange has;
Lower disk flange, disk and oil hydraulic cylinder are formed closed no leakage space, and damp liquid is full of this closed no leakage space, this oil hydraulic cylinder part be positioned at the cylinder that the upper end has disc flange, the upper end has built-in second permanent magnetic iron block of cylinder of disc flange;
This nothing is leaked the rotating fluid damper and is also comprised rotor blade, circular shaft, stator blade, Hollow Cylindrical Shaft and first permanent magnetic iron block, and Hollow Cylindrical Shaft is enclosed within on the circular shaft, and the height of the height of Hollow Cylindrical Shaft and circular shaft is identical; Rotor blade is positioned at the inside of oil hydraulic cylinder; The height of this rotor blade is identical with the height of oil hydraulic cylinder, and rotor blade links to each other with Hollow Cylindrical Shaft near an end in the center of circle, and rotor blade contacts with oil hydraulic cylinder is smooth away from an end in the center of circle; And the upper end of rotor blade contacts with disk is smooth; The lower end of rotor blade contacts with the lower disk flange is smooth, and rotor blade is along highly having little round tube hole, the axis of little round tube hole and the orthogonal axe of circular shaft; When damp liquid when the roundlet through hole, during the suffered damping force reduction of force system of rotor blade some to the circular shaft axis, the main arrow is zero, the acting surface of main square and the axis normal of circular shaft; Stator blade links to each other with oil hydraulic cylinder away from an end in the center of circle; Stator blade contacts with Hollow Cylindrical Shaft is smooth near an end in the center of circle; First permanent magnetic iron block is arranged on rotor blade inside; The circular shaft lower end surface does not have leakage with the lower disk flange and is connected, and the upper-end surface of circular shaft flushes with the upper-end surface of disk and do not have to leak and is connected; Rotor blade evenly distributes along Hollow Cylindrical Shaft cylindrical contour, and stator blade evenly distributes along oil hydraulic cylinder inner circumference line, and is provided with a rotor blade in the middle of per two stator blades.
Second permanent magnetic iron block is identical with the first permanent magnetic iron block quantity; The position is corresponding one by one, and second permanent magnetic iron block and first permanent magnetic iron block attract each other through magnetic force, and the suffered magnetic force of second permanent magnetic iron block system is when being simplified to some on the circular shaft axis; The main arrow is zero, the acting surface of main square and the axis normal of circular shaft; When the suffered magnetic force of first permanent magnetic iron block system was simplified to some on the circular shaft axis, the main arrow was zero, the acting surface of main square and the axis normal of circular shaft.
The upper end has the axis of the cylinder of disc flange, the axis of circular shaft, the axis of Hollow Cylindrical Shaft, the axis of disk, the axis of oil hydraulic cylinder and the dead in line of bottom disc flange.
In this no leak fluid damper, add spring, obtain not having the another kind of style of leakage current variant damper; The upper end of spring is connected the upper end and has on the lower end surface of upper end disc flange of cylinder of disc flange, and the lower end of spring is connected on the upper surface of disk.
The roundlet through hole can change and is located on the stator blade axis of little round tube hole and the orthogonal axe of circular shaft.
Have little round tube hole on stator blade and the rotor blade simultaneously, the axis of little round tube hole and the orthogonal axe of circular shaft.
During use; The upper end disc flange that the upper end has the cylinder of disc flange is fixed on the oscillating body (or static basis); The upper surface of upper end disc flange that the upper end has the cylinder of disc flange contacts with oscillating body (or static basis), and the lower disk flange is fixed on the static basis (or oscillating body); The upper end has the axis of the cylinder of disc flange, the axis of lower disk flange, the axis of cylindrical shape oil hydraulic cylinder, the axis of disk, the axis of circular shaft, the axis of Hollow Cylindrical Shaft and the dead in line of spring.Because first permanent magnetic iron block in the rotor blade has the magnetic attraction effect between second permanent magnetic iron block in the cylinder of disc flange with the upper end; When oscillating body is static; Be in the static balance state under the rotor blade magnetic force, and be positioned at the centre of two stator blades; When oscillating body vibrates; The cylinder that the upper end has a disc flange will draw rotor blade and rotate around circular shaft; When rotor blade rotates, damp liquid will flow through the little round tube hole on the rotor blade, and damp liquid flows through the roundlet through hole dissipative structure vibrational energy on the rotor blade.
Beneficial effect:Oil hydraulic cylinder, bottom disc flange, disk are formed does not have the confined space of leakage; Blade is rotated around circular shaft in this confined space by Magnetic force tracting, and when blade rotation, damp liquid flows through the little round tube hole on the blade; Damp liquid consumes energy when flowing through the roundlet through hole on the blade, plays the effect that suppresses vibration.Owing to do not use Sealing, blade does not only rotate in having the confined space of leakage, and the phenomenon of leakage of general fluid damper in the vibration control process can not appear in this fluid damper.The distance of first permanent magnetic iron block and second permanent magnetic iron block can be very near, do not receive the influence of vibration displacement, presses the electromagnetism principle, and magnetic force is bigger, thereby bigger damping force can be provided.
