In this paper, the authors propose a passive type MR damper which has hardening type resisting force characteristic. The damper consists of a piston, a cylinder, MR fluid and rare-earth magnets which are attached symmetrically about the center of the cylinder. A trial damper was made and the resisting force characteristic was measured. A semi-active type MR damper with a bypass was also made to compare the passive type MR damper. The frequency and seismic responses of a single-degree-of-freedom system supported with the MR dampers were measured with a shaking table using permanent magnets. The effects of vibration suppression of both dampers were compared, and the equality of the passive type MR damper with the semi-active type MR damper was substantiated. The experimental results were compared with calculated results, and the validity of the calculations was confirmed.
