| 摘要 |
A method for controlling the damping force of a damper containing a movable object in a magneto-rheological fluid, in which a positive magnetic field is applied to the fluid to achieve an increase in viscosity (and an increase in damping force) and the polarity of the magnetic field is reversed by negative electrical energy to remove residual magnetism before reestablishing the magnetic field at a lower level to achieve a predictable decrease in viscosity (and a decrease in damping force).
