Description
Technical field
The invention belongs to a kind of vibration damper, be specifically related to a kind of two board-like vibration damper of rod magnetorheological elastomer.
Background technique
MR damper is a kind of intelligent vibration damper, in the time that this class damper adopts magnetic flow liquid to be resisting medium, mainly be applicable to ocsillator strenght compared with vibration damping occasion little and that Oscillation Amplitude is larger, as: application number: 200410079249.2 " a kind of magnetorheological suspensions damping device for automobile suspension system ", because this class damper is difficult to be applicable to the vibration damping occasion that ocsillator strenght is less compared with large Oscillation Amplitude (as: vibration damping of jumbo), and the of the present invention pair of board-like vibration damper of outstretch pole magnetorheological elasticity is using magnetic rheology elastic body as resisting medium and adopts 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 by adjusting its diameter and the number of plies.
Summary of the invention
Be difficult to be applicable to ocsillator strenght compared with vibration damping occasion large and that amplitude is less in order to overcome existing magnetic rheological liquid damper, the present invention proposes a kind of two board-like vibration damper of rod magnetorheological elastomer.
Technological scheme of the present invention is as follows: a kind of two board-like vibration dampers of rod magnetorheological elastomer, it comprises clutch release slave cylinder, piston and piston rod, wherein: clutch release slave cylinder is that Single sided electromagnet, N piece identical Double-face ring electromagnet and the outer tube identical by two forms, and two blocks of Single sided electromagnet are separately fixed at the two ends of outer tube, N piece Double-face ring electromagnet is fixed on the inner circumference of two outer tubes between Single sided electromagnet in parallel to each other, and the gap between each ring electromagnet is equated; Sliding bearing is all installed on the internal diameter of two blocks of Single sided electromagnet; Piston is made up of N+1 piece annular iron plate, all bonding magnetic rheology elastic body of one deck same thickness on two toroidal surfaces of every annular iron plate, and piston rod is through the mesopore of N+1 piece annular iron plate fixing with it; Piston is arranged in clutch release slave cylinder, N+1 piece annular iron plate on piston is placed in the gap between the interior each ring electromagnet of clutch release slave cylinder, and making the toroidal surface of magnetic rheology elastic body on two toroidal surfaces of annular iron plate on piston and each ring electromagnet bonding, stretch out from the two ends of clutch release slave cylinder respectively by the sliding bearing on the Single sided electromagnet internal diameter at clutch release slave cylinder two ends at the two ends of piston rod; Gap in clutch release slave cylinder between each ring electromagnet equals magnetic rheology elastic body thickness sum on the thickness of annular iron plate on piston and two toroidal surface; Single sided electromagnet only has on a toroidal surface and is evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, is wound with field coil; On two toroidal surfaces of Double-face ring electromagnet, be all evenly equipped with at least 4 pairs of magnetic poles, on each magnetic pole, be wound with field coil; The internal diameter of Double-face ring electromagnet is greater than the diameter of piston rod and leaves free gap; On piston, the external diameter of annular iron plate is less than the internal diameter of clutch release slave cylinder urceolus and leaves free gap.
