In this paper, the basic characteristics of "Ball Screw Type Magnetic Friction Damper" are investigated. "Ball Screw Type Magnetic Friction Damper" is a kind of friction damper. Ball Screw is used to increase the sliding displacement by changing translation into rotation. Restoring force occurs mainly by friction force between rotation disk and fixed disk with permanent magnet. In this study, a small product of the damper is made. The characteristics of the damper are examined by the results from shaking test and the results of numerical analysis. The numerical model of this damper is applied the damper to one degree of freedom system in order to investigate response magnification of this system. Permanent magnet is changed into an electromagnet to control the resting force. Possibility of the damper as a semi-active one is investigated.
