PURPOSE: An active vibration reduction device using an MR(Magneto-Rheological) fluid is provided to actively perform resonance avoidance on the vibration applied from the outside and reduce the vibration level. CONSTITUTION: An active vibration reduction device using an MR fluid comprises a main body(10), cover units(20,30), and a bobbin unit. The main body comprises a fluid space in which the MR fluid is filled. The cover unit closes an end of the main body and supplies electric signals to the bobbin unit. The bobbin unit is inserted into the main body and changes the viscosity of the MR fluid by controlling the magnetic field according to the electric signals transferred through the cover unit. |
