Abstract

The invention relates to a current variant damper which comprises an upper part and a lower part which are mutually independent, wherein the upper part of the current variant damper comprises an upper disc flange, a first permanent magnet and a first pressing block; the first permanent magnet is fixed in the upper disc flange through the first pressing block; and the action line of the resultant force of the magnetic forces stressed by the first permanent magnet coincides with the axis of a hollow circular shaft. The current variant damper provided by the invention utilizes the magnetic forces and a spring to push a piston in the damper to move; when the piston moves, a current variant flows through a small circular through hole on the piston; when the current variant flows through the small circular through hole on the piston, energy is consumed; and the viscosity of the current variant is changed by changing the voltage between a positive plate and a negative plate according to vibration control requirements, thereby achieving the effect of actively controlling vibration. Because a dynamic sealing element is not used, the damper provided by the invention is not easy to leak damping fluid.
