Aiming at the limitation of energy in quakeproof,aerospace and field ordnance,and requirements for damper's different damping force in vehicle vibration's pull and press stroke,a passive adaptive MR damper is designed and made.The damper transforms the variation of load force into the variation of magnetic field through the MRF based on GMM inverse effect and characteristics of MRF,and solves the problem that ordinary damper control requires external energy installations and control circuit.A model of passive adaptive MR damping is established and damping feature experiment is done.The result shows that damping force is related to load force: the greater the tension,the greater the damping force;the greater the pressure,the smaller the damping force.The damper has characteristic of adaptive load,and the feasibility of the design is verified.
