In the previous paper, the authors proposed a new type of passive magnetic damper using rare-earth magnets and a lever-type displacement magnifying mechanism, which gives damping within a relative displacement in the region of about 0.1〜10 mm. In this paper, two types of vibration systems in which the damper is supported elastically were discussed analytically and experimentally in order to make the magnetic damper useful in wide frequency range. The trial damper was made and the resisting force characteristics were measured. The frequency responses and seismic responses of three types of the vibration system elastically supported by the magnetic damper were measured using an electrohydraulic type shaking table. The experimental results are compared with the calculated results and the effects of vibration suppression of the magnetic damper and the elastic support in wide frequency range are discussed.
