Description
Technical field
The utility model belongs to a kind of vibration damper, is specifically related to the board-like vibration damper of a kind of single outstretch pole magnetorheological elastomer.
Background technique
MR damper is a kind of intelligent vibration damper; When this type damper adopts magnetic flow liquid to be resisting medium; Be applicable to mainly that ocsillator strenght is less and vibration damping occasion that Oscillation Amplitude is bigger; As: application number: 200410079249.2 " a kind of magnetorheological suspensions damping device for automobile suspension system "; Because of this type damper is difficult to be applicable to the big less vibration damping occasion (as: vibration damping of jumbo) of Oscillation Amplitude of ocsillator strenght; And the board-like vibration damper of single outstretch pole magnetorheological elasticity of the utility model be with magnetic rheology elastic body as resisting medium and adopt disk and multi-layer structure, therefore, the single outstretch pole magnetorheological elasticity of the utility model subtracts the board-like device that shakes can adjust its bearing capacity through adjusting its diameter and the number of plies.
Summary of the invention
Be difficult to be applicable to that in order to overcome existing magnetic rheological liquid damper ocsillator strenght is big and the less vibration damping occasion of amplitude the utility model provides the board-like vibration damper of a kind of single outstretch pole magnetorheological elastomer.
The technological scheme of the utility model is following: the board-like vibration damper of a kind of single outstretch pole magnetorheological elastomer; It comprises clutch release slave cylinder, piston and piston rod; Wherein: clutch release slave cylinder is to be made up of a Single sided electromagnet, single face dish type electromagnet, two-sided ring electromagnet and outer tube that the N piece is identical; And the Single sided electromagnet is fixed on an end of outer tube, and single face dish type electromagnet is fixed on the other end of outer tube, on the internal diameter of Single sided electromagnet, sliding bearing is installed; The two-sided ring electromagnet of N piece is fixed on the inner circumference of the outer tube between Single sided electromagnet and the single face dish type electromagnet in parallel to each other, and the gap between each electromagnet is equated; Piston is made up of N+1 piece annular iron plate, and all bonding magnetic rheology elastic body of one deck same thickness on two toroidal surfaces of every annular iron plate, an end of piston rod pass the mesopore of N+1 piece annular iron plate and fixing with it; Piston is installed in the clutch release slave cylinder; N+1 piece annular iron plate on the piston is placed in the gap between interior each electromagnet of clutch release slave cylinder; And making the toroidal surface of magnetic rheology elastic body and each electromagnet on two toroidal surfaces of annular iron plate on the piston bonding, the other end of piston rod stretches out through the end of the sliding bearing on the Single sided electromagnet internal diameter of clutch release slave cylinder one end from clutch release slave cylinder; Gap in the clutch release slave cylinder between each electromagnet equals magnetic rheology elastic body thickness sum on thickness and its two toroidal surfaces of annular iron plate on the piston; The Single sided electromagnet has only on the toroidal surface and is evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, all is wound with field coil; Single face dish type electromagnet has only on the disc and is evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, all is wound with field coil; All be evenly equipped with at least 4 pairs of magnetic poles on two toroidal surfaces of two-sided ring electromagnet, on each magnetic pole, all be wound with field coil; The internal diameter of two-sided ring electromagnet is greater than the diameter of piston rod and leave the free gap; The external diameter of annular iron plate is less than the internal diameter of clutch release slave cylinder urceolus and leave the free gap on the piston.
The function of the utility model is achieved in that because all bonding one deck magnetic rheology elastic body on two toroidal surfaces of each annular iron plate on the piston; And each annular iron plate places in the gap between interior each electromagnet of clutch release slave cylinder; The magnetic rheology elastic body on its two sides is bonding with the toroidal surface (that is: magnetic pole strength) of each electromagnet again; Therefore; When piston rod drove piston and in clutch release slave cylinder, moves, the magnetic rheology elastic body between each electromagnet took place to stretch or compress in each annular iron plate of being in piston and the clutch release slave cylinder with making; When the field coil of each electromagnet does not have electric current to pass through; Each electromagnet does not generate an electromagnetic field; Make the elasticity of the magnetic rheology elastic body between each electromagnet in each the annular iron plate that is in piston and the clutch release slave cylinder less, it is less to make piston rod drive the damping force that receives when piston moves in clutch release slave cylinder; When the field coil of each electromagnet has electric current to pass through; Each ring electromagnet will generate an electromagnetic field; Owing to be evenly equipped with at least 4 pairs of magnetic poles on the toroidal surface of each electromagnet; Therefore; Every pair of magnetic pole on the electromagnet will form closed magnetic circuit through the magnetic rheology elastic body between the annular iron plate, makes the ferromagnetic particle in the magnetic rheology elastic body that is on the closed magnetic circuit form chain or column aggregated structure and make its elasticity higher at magnetic direction, and it is bigger to make piston rod drive the damping force that receives when piston moves in clutch release slave cylinder; Therefore; Get into the size of current in each electromagnet through adjustment; Can adjust the electromagnetic field intensity that each electromagnet produces; Make the elasticity size of the magnetic rheology elastic body between each electromagnet in each the annular iron plate that is on the piston and the clutch release slave cylinder obtain adjustment, thereby make the damping force of the board-like vibration damper of single outstretch pole magnetorheological obtain adjustment.
The board-like vibration damper of the single outstretch pole magnetorheological of the utility model also can be adjusted its bearing capacity through adjusting its diameter and the number of plies, and the board-like vibration damper of single outstretch pole magnetorheological elastomer of comparing the utility model with magnetic rheological liquid damper more can be applicable to the big and less vibration damping occasion of amplitude of ocsillator strenght.
