Description
Technical field
The invention belongs to a kind of vibration damper, be specifically related to a kind of pair of board-like vibration damper of 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 of the present invention pair of board-like vibration damper of outstretch pole magnetorheological elasticity be with magnetic rheology elastic body as resisting medium and adopt disk and multi-layer structure, therefore, of the present invention pair of outstretch pole magnetorheological elasticity subtracts the board-like device that shakes and 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 present invention proposes a kind of pair of board-like vibration damper of outstretch pole magnetorheological elastomer.
Technological scheme of the present invention is following: a kind of pair of board-like vibration damper of outstretch pole magnetorheological elastomer; It comprises clutch release slave cylinder, piston and piston rod, and wherein: clutch release slave cylinder is to be made up of two Single sided iron plates, identical two-sided annular iron plate and the outer tube of two-sided ring electromagnet, N-1 piece that the N piece is identical; Bonding one deck magnetic rheology elastic body has all been installed sliding bearing on the toroidal surface of Single sided iron plate on the internal diameter of two Single sided iron plates, and two Single sided iron plates are separately fixed at the two ends of outer tube; The all bonding magnetic rheology elastic body of one deck same thickness on two toroidal surfaces of two-sided annular iron plate, the two-sided annular iron plate of N-1 piece is fixed on the inner circumference of two outer tubes between the Single sided iron plate abreast by identical distance; Piston is made up of the two-sided ring electromagnet of N piece, and piston rod passes the mesopore of the two-sided ring electromagnet of N piece and fixing with it; Piston is installed in the clutch release slave cylinder; Make the two-sided ring electromagnet of N piece on the piston place interior each the annular iron plate of clutch release slave cylinder to go up in the gap between the magnetic rheology elastic body; And making in the clutch release slave cylinder on the magnetic rheology elastic body on each annular iron plate toroidal surface and piston the toroidal surface of each two-sided ring electromagnet bonding, stretch out from the two ends of clutch release slave cylinder respectively through the sliding bearing on the Single sided iron plate internal diameter of clutch release slave cylinder two ends at the two ends of piston rod; Gap in the clutch release slave cylinder between the last magnetic rheology elastic body of each annular iron plate equals the thickness of two-sided ring electromagnet on the piston; 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 annular iron plate is greater than the diameter of piston rod and leave the free gap; The external diameter of two-sided ring electromagnet is less than the internal diameter of clutch release slave cylinder urceolus and leave the free gap on the said piston.
Function of the present invention is achieved in that because all bonding one deck magnetic rheology elastic body on the toroidal surface of each annular iron plate in the clutch release slave cylinder; After in piston is installed in clutch release slave cylinder; The two-sided ring electromagnet of N piece on the piston places interior each the annular iron plate of clutch release slave cylinder to go up in the gap between the magnetic rheology elastic body; And make in the clutch release slave cylinder on the magnetic rheology elastic body on each annular iron plate toroidal surface and piston the toroidal surface (that is: magnetic pole strength) of each two-sided ring electromagnet bonding; Therefore, when piston rod drives piston and in clutch release slave cylinder, moves, the magnetic rheology elastic body between each annular iron plate in each the two-sided ring electromagnet and the clutch release slave cylinder that make on the piston is taken place to stretch or compress; When the field coil of each two-sided ring electromagnet on the piston does not have electric current to pass through; Each two-sided ring electromagnet does not generate an electromagnetic field; Make the elasticity that is in the magnetic rheology elastic body between each two-sided ring electromagnet on each interior annular iron plate of clutch release slave cylinder and the piston 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 two-sided ring electromagnet on the piston has electric current to pass through; Each two-sided ring electromagnet will generate an electromagnetic field; Owing to all be evenly equipped with at least 4 pairs of magnetic poles on two toroidal surfaces of two-sided ring electromagnet; Therefore; Every pair of magnetic pole on the piston on two toroidal surfaces of two-sided ring electromagnet will through and clutch release slave cylinder in magnetic rheology elastic body between the annular iron plate form closed magnetic circuit, make 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, 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 two-sided ring electromagnet on the piston through adjustment; Can adjust the electromagnetic field intensity that each two-sided ring electromagnet produces; Make the elasticity size of the magnetic rheology elastic body between each annular iron plate in each the two-sided ring electromagnet that is on the piston and the clutch release slave cylinder obtain adjustment, thereby make the damping force of two board-like vibration dampers of outstretch pole magnetorheological obtain adjustment.
The of the present invention pair of board-like vibration damper of outstretch pole magnetorheological also can be adjusted its bearing capacity through adjusting its diameter and the number of plies, compares the of the present invention pair of board-like vibration damper of outstretch pole magnetorheological elastomer with magnetic rheological liquid damper and more can be applicable to the big and less vibration damping occasion of amplitude of ocsillator strenght.
