Description
Technical field
The invention belongs to a kind of vibration damper, be specifically related to a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper.
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 adopts magnetic flow liquid is that the damper of resisting medium is difficult to be applicable to the big less vibration damping occasion (as: vibration damping of jumbo) of Oscillation Amplitude of ocsillator strenght; And a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper of the present invention be with magnetic rheology elastic body as resisting medium and adopt rectangle plane and multi-layer structure, therefore, a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper of the present invention can be adjusted its bearing capacity through adjusting its rectangular area 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 outstretch pole magnetorheological elastomer rectangle vibration damper.
Technological scheme of the present invention is following: a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper; It comprises clutch release slave cylinder, piston and piston rod, and wherein: clutch release slave cylinder is to be made up of two identical two-sided rectangle electromagnet and rectangle outer tubes of identical single face rectangle electromagnet, N piece; On two intersection of diagonal of single face rectangle electromagnet, mesopore is arranged; Sliding bearing is installed in mesopore; Two blocks of single face rectangle electromagnet are separately fixed at the two ends of rectangle outer tube, and the two-sided rectangle electromagnet of N piece is fixed on the inner chamber of two rectangle outer tubes between the single face rectangle electromagnet abreast by identical distance; Piston is made up of the two-sided rectangle iron plate of N+1 piece; The all bonding magnetic rheology elastic body of one deck same thickness on two rectangle planes of every two-sided rectangle iron plate; On two intersection of diagonal of every two-sided rectangle iron plate, mesopore is arranged all, an end of piston rod passes the mesopore of the two-sided rectangle iron plate of N piece and fixing with it; Piston is installed in the clutch release slave cylinder; The two-sided rectangle iron plate of N piece on the piston is placed in the gap between interior each the rectangle electromagnet of clutch release slave cylinder; And make on rectangle plane and the piston of each rectangle electromagnet in the clutch release slave cylinder magnetic rheology elastic body on each two-sided rectangle iron plate bonding; Stretch out in clutch release slave cylinder through the sliding bearing on the single face rectangle electromagnet of clutch release slave cylinder two ends respectively at the two ends of piston rod; Gap in the clutch release slave cylinder between each rectangle electromagnet equals the thickness of two-sided rectangle iron plate on the piston and the magnetic rheology elastic body thickness sum on its two rectangular surfaces, and the iron core of two-sided rectangle electromagnet is certain thickness rectangular block, on two of rectangular block parallel rectangle planes, respectively is evenly equipped with at least 4 pairs of magnetic poles; On each magnetic pole, all be wound with field coil; And the diameter of two-sided rectangle electromagnet mesopore is greater than the diameter of piston rod and leave the free gap, and the iron core of single face rectangle electromagnet is certain thickness rectangular block, on a rectangle plane of rectangular block, is evenly equipped with at least 4 pairs of magnetic poles; On each magnetic pole, all be wound with field coil, the length of two-sided rectangle iron plate and width are less than the length and the width of clutch release slave cylinder rectangle outer tube bore longitudinal plane and leave the free gap.
Function of the present invention is achieved in that because all bonding magnetic rheology elastic body of one deck same thickness on the surface of each two-sided rectangle iron plate on the piston; Therefore; After in piston is installed in clutch release slave cylinder; After the two-sided rectangle iron plate of on the piston each places in the clutch release slave cylinder in the gap between each rectangle electromagnet, make the rectangle plane (that is: magnetic pole strength) of each interior rectangle electromagnet of the magnetic rheology elastic body on the two-sided rectangle iron plate and clutch release slave cylinder on the piston bonding, therefore; When piston rod drives piston and in clutch release slave cylinder, moves, the magnetic rheology elastic body between each rectangle electromagnet in each the two-sided rectangle iron plate and the clutch release slave cylinder that make on the piston is taken place to stretch or compress; When the field coil of each rectangle electromagnet in the clutch release slave cylinder does not have electric current to pass through; Each rectangle electromagnet does not generate an electromagnetic field; Make the elasticity of the magnetic rheology elastic body between each the rectangle electromagnet in each the rectangle iron plate that is on the 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 rectangle electromagnet in the clutch release slave cylinder has electric current to pass through; Each rectangle electromagnet will generate an electromagnetic field; Owing to all be evenly equipped with at least 4 pairs of magnetic poles on each rectangle plane of each rectangle electromagnet; Therefore; Every pair of magnetic pole in the clutch release slave cylinder on the rectangle plane of each rectangle electromagnet will through and piston on each rectangle iron plate between magnetic rheology elastic body 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 rectangle electromagnet in the clutch release slave cylinder through adjustment; Can adjust the electromagnetic field intensity that each rectangle electromagnet is produced; Make the elasticity size that is in each interior rectangle electromagnet of clutch release slave cylinder and the magnetic rheology elastic body between each the two-sided rectangle iron plate on the piston obtain adjustment, thereby make the damping force of a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper obtain adjustment.
A kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper of the present invention also can be adjusted its bearing capacity with the number of plies through adjusting its rectangular area size, compares a kind of pair of outstretch pole magnetorheological elastomer rectangle vibration damper of the present invention with magnetic rheological liquid damper and can be applicable to that more ocsillator strenght greatly and the less vibration damping occasion of amplitude.
