The utility model has the advantage of a simple structure, reliable performance, low price, the capability of realizing intelligent vibration control through a single chip microcomputer and good damping effect, and has relatively wide application prospects in the automobile and civil structures needing higher damping effect.
Description
(1) technical field
The utility model relates to a kind of vibration damper.
(2) background technique
In automobile and civil structure vibration control, mainly adopted the vibration damper of passive energy consumption form in the past.Damping energy dissipation element and shock absorption system promptly are set, the energy of dissipative structure vibration, thereby the power reflection that alleviates structure in structure.The vibration damper of this structural type, ubiquity energy consumption height, response time length, system complex, non-adjustable, cost is high, be difficult to the deficiencies such as effectiveness in vibration suppression that reach desirable.
(3) summary of the invention
The purpose of this utility model is to provide a kind of damping force to adjust rapidly, the shearing valve type magneto-rheological fluid vibration damping driver of good damping result.The purpose of this utility model is achieved in that it comprises cylinder shell, piston is set in cylinder shell, connect piston rod on the piston, have groove on the piston, twine field coil in the groove, be connected with lead on the field coil, lead passes piston and links to each other with controller, be filled with magnetic flow liquid in the cylinder shell, gapped between piston and the cylinder shell inwall, at the two ends of cylinder shell the resistance magnet ring is set.The utility model can also comprise following structure characteristic: (1) two ends in cylinder shell are provided with seal; (2) between the resistance magnet ring of lower end and the cylinder shell bottom piston rod mobile cavity is arranged.Advantage of the present utility model is: utilized magnetic flow liquid under the action of a magnetic field, can be in Millisecond moment, Newtonian fluid rheology by the good fluidity under zero magnetic field condition is the characteristic of the Bingham body of the lazy flow under the high magnetic fields condition, when piston motion, the magnetic flow liquid in the vibration damper will be forced to enter the other end from an end of piston by the gap between piston and the cylinder shell inwall.Change owing to the magnetic flow liquid that flows through the gap can produce viscosity along with the variation of gap internal magnetic field, so corresponding variation also can take place in the resistance to motion of piston.Thereby, can regulate the size that mode that the gap internal magnetic field changes is regulated vibration damper power by the size of current that adjusting is wrapped in the coil on the piston.The utility model by magnetic Circuit Design cleverly, makes oil hydraulic cylinder under the situation of perfusion magnetic flow liquid on the basis of common oil hydraulic cylinder, had damping force along contrary characteristic of regulating continuously, and governing speed is exceedingly fast, energy consumption is very low.Solved existing vibration insulating system and lacked a difficult problem simple, reliable, inexpensive, equipment that can be by the control of chip microcontroller intelligent vibration, this has comparatively wide application prospect in the automobile of the higher effectiveness in vibration suppression of needs and civil structure.
