In this paper, an arm-type damper consisting of a link of variable length and two universal joints incorporating air damper has developed. The arm-type damper is able to suppress six modes of vibration of a machine, three in translational and three in rotational modes. An air damper was used for the link and two frictional joints were used for the universal joints. The trial arm-type damper was made and the resisting force characteristics in the three translational directions were measured. The seismic responses of a three-degree-of freedom linear system consisting of a mass, four coil springs and six linear guides, supported by the arm-type damper, were also measured using a two-dimensional electrohydraulic type shaking table. The experimental results are compared with the calculated ones, and the effects of vibration suppression of the arm-type damper for three translational directions are discussed.
