Damping control device filled with magnetorheological fluid and engine mount having the same

摘要

A damping control device includes a lower core, a nonmagnetic orifice, an upper core, and a membrane made of an elastic material to shield a lower end of the lower core, and in which the lower core and the upper core are magnetized when a current is applied to the coil, and a predetermined amount of the MR fluid is filled therein, such that the MR fluid flows between the pressure applying plate and the upper plate according to an elastic compression of the membrane.
