- Abstract:
- The damper is capable of providing a continuously variable dampering force/torque in response to a magnetic field.It consists of an upside cap and an underside cap with a rotor located between them, the magneto-rheological(MR)fluid is filled into the gaps between the rotor and the caps.When the viscosity of the MR fluid increases under the influence of the magnetic field, the movement of the rotor will be resisted.The output torque is made up of the torque caused by the magnetic field, the torque caused by the plastic viscosity of the MR fluid, and the torque caused by the coulomb friction.The viscous torque can be calculated by a simple method and the frictional torque can be obtained by experiments. The torque dependent on the magnetic field is obtained by electromagnetic finite element analysis.Experiments are done on the damper prototype and the validity of the design is verified.
