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 class 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 ", the damper that is resisting medium because of this class employing magnetic flow liquid 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 outstretch pole magnetorheological elastomer rectangle vibration damper is as resisting medium and adopt rectangle plane and multi-layer structure with magnetic rheology elastic body, therefore, of the present invention pair of outstretch pole magnetorheological elastomer rectangle vibration damper can be adjusted its bearing capacity by 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 as follows: 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 of two identical two-sided rectangle iron plate and rectangle outer tubes of identical single face rectangle iron plate, N-1 piece; Bonding one deck magnetic rheology elastic body on the rectangle plane of single face rectangle iron plate, two intersection of diagonal on single face rectangle iron plate have mesopore, sliding bearing is installed in mesopore, and two identical single face rectangle iron plates are separately fixed at the two ends of rectangle outer tube; The all bonding magnetic rheology elastic body of one deck on two rectangle planes of two-sided rectangle iron plate, the two-sided rectangle iron plate of N-1 piece is fixed on the inner chamber of two rectangle outer tubes between the single face rectangle iron plate abreast by identical distance; Piston is made of the two-sided rectangle electromagnet of N piece, on two intersection of diagonal of the two-sided rectangle electromagnet of N piece mesopore is arranged, 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 rectangle electromagnet of N piece on the piston place each rectangle iron plate in the 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 rectangle iron plate and piston two rectangle planes of each two-sided rectangle electromagnet bonding, stretch out in clutch release slave cylinder by the sliding bearing on the single face rectangle iron plate of clutch release slave cylinder two ends respectively at the two ends of piston rod.Gap in the clutch release slave cylinder between the last magnetic rheology elastic body of each rectangle iron plate equals the thickness of two-sided rectangle electromagnet on the piston.The iron core of two-sided rectangle electromagnet is certain thickness rectangular block, respectively is evenly equipped with at least 4 pairs of magnetic poles on two of rectangular block parallel rectangle planes, is wound with field coil on each magnetic pole; The length of the rectangle iron core of two-sided rectangle electromagnet and width are less than length and the width of clutch release slave cylinder rectangle outer tube bore longitudinal plane and leave the free gap, the diameter of two-sided rectangle iron plate mesopore is greater than the diameter of piston rod and leave the free gap, and N is not less than 1 natural number.
Function of the present invention is achieved in that because all bonding one deck magnetic rheology elastic body on the surface of each rectangle iron plate in the clutch release slave cylinder, after in piston is installed in clutch release slave cylinder, the two-sided rectangle electromagnet of N piece on the piston places each rectangle iron plate in the 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 rectangle iron plate and piston two rectangle planes (that is: magnetic pole strength) of each two-sided rectangle electromagnet bonding, therefore, when piston rod drives piston and moves in clutch release slave cylinder, the magnetic rheology elastic body between each rectangle iron plate in each the two-sided rectangle 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 rectangle electromagnet on the piston does not have electric current to pass through, each two-sided rectangle electromagnet does not generate an electromagnetic field, make the elasticity that is in the magnetic rheology elastic body between each two-sided rectangle electromagnet on each interior rectangle iron plate of clutch release slave cylinder and the piston less, it is less to make piston rod drive the damping force that is subjected to when piston moves in clutch release slave cylinder; When the field coil of each two-sided rectangle electromagnet on the piston has electric current to pass through, each two-sided rectangle electromagnet will generate an electromagnetic field, owing to be evenly equipped with at least 4 pairs of magnetic poles on each rectangle plane of two-sided rectangle electromagnet, therefore, every pair of magnetic pole on the piston on two rectangle planes of two-sided rectangle electromagnet will by and clutch release slave cylinder in magnetic rheology elastic body between the rectangle 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 is subjected to when piston moves in clutch release slave cylinder; Therefore, enter the size of current in each two-sided rectangle electromagnet on the piston by adjustment, can adjust the electromagnetic field intensity that each two-sided rectangle electromagnet produces, make the elasticity size of the magnetic rheology elastic body between each rectangle iron plate in each two-sided rectangle electromagnet of being on the piston and the clutch release slave cylinder obtain adjusting, thereby make the damping force of two outstretch pole magnetorheological elastomer rectangle vibration dampers obtain adjusting.
Of the present invention pair of outstretch pole magnetorheological elastomer rectangle vibration damper also can be adjusted its bearing capacity by adjusting its rectangular area size and the number of plies, compares of the present invention pair of outstretch pole magnetorheological elastomer rectangle vibration damper with magnetic rheological liquid damper and more can be applicable to ocsillator strenght greatly and the less vibration damping occasion of amplitude.
