Abstract:
1. A vibration damping system comprising: a vibration damping body including a laminated body wherein a plurality of hard plates having a rigidity and a plurality of soft members having a viscoelasticity are alternately laminated with each other, and a pair of shoe plates on both end portions of the laminated body in the laminating direction, and further comprising a displacement restriction member for connecting the pair of the shoe plates with each other for providing a pre-compression to the laminated body, wherein the vibration damping body is divided into a plurality of segments in the laminating direction, the hard plates are arranged on each parting face in the vibration damping body of the segment, the hard plates on parting faces of adjacent segments directly contact each other and are provided with a restriction portion that restricts a relative movement in at least one of a shearing direction and a rotating direction, and each of said segments is an integral unit comprising a plurality of said hard plates and a plurality of said soft members, each of said hard plates and said soft members are alternately laminated with each other.
