In this paper, the authors propose a new type of hybrid magnetic damper using a lever-type displacement magnifying mechanism, which gives damping within a relative displacement in the region of about 0.1∿10mm. The trial damper was made and the resisting force characteristics were measured. The frequency responses and seismic responses of a three-dimensional piping system supported by the damper were measured using an electrohydraulic type shaking table. The experimental results are compared with the calculated results obtained by the FEM software (ANSYS), and the effects of vibration suppression of the hybrid damper are discussed.
