Abstract
A vibration damping system includes a laminated body () formed by alternately laminating rigid hard plates () and viscoelastic soft plates (), and pair of shoe plates () at both ends in the laminating direction of the laminated body (), to form a vibration damping body (). The show plates () are connected to each other by a displacement restriction member (), so as to applying a pre-compression to the laminated body. The vibration damping body () is divided into a plurality of segments (A,B,C) in the laminating direction, for allowing the vibration-proof main body () to be separated and displaced at the parting faces (), without causing an excessive tensile force in the vibration damping system, even if the displacement restriction member () has worn to degrade the pre-compression function and a tensile force is applied due to a prying deformation. Thus, the soft members () of the laminated body () are effectively protected from isostatic fracture, to provide a significantly improved durability of the vibration damping system.
