In order to study the properties of the new kind of smart controllable fluid magnetorheological(MR) fluid,the magnetic particles, which is one of the main components of the MR fluid are discussed in this paper. Also, the rheological models are discussed. On the basis of analyzing the structure forms of the MR dampers, an improved structure of MR damper is suggested. Then the properties of the novel MR damper are tested and several key parameters, which can affect the properties of the MR damper, are analyzed. At last, the main unsolved problems have been put forward.
