| Abstract: | A vibration damping system includes a laminated body (3) formed by
alternately laminating rigid hard plates (4) and viscoelastic soft plates
(5), and pair of shoe plates (1, 2) at both ends in the laminating
direction of the laminated body (3), to form a vibration damping body
(6). The show plates (1, 2) are connected to each other by a displacement
restriction member (7), so as to applying a pre-compression to the
laminated body. The vibration damping body (6) is divided into a
plurality of segments (3A, 3B, 3C) in the laminating direction, for
allowing the vibration-proof main body (6) to be separated and displaced
at the parting faces (8), without causing an excessive tensile force in
the vibration damping system, even if the displacement restriction member
(7) has worn to degrade the pre-compression function and a tensile force
is applied due to a prying deformation. Thus, the soft members (5) of the
laminated body (3) are effectively protected from isostatic fracture, to
provide a significantly improved durability of the vibration damping
system. |
