Abstract:
1. A vibration damping system comprising: a laminated body including a plurality of hard plates having a rigidity, and a plurality of soft members having a viscoelasticity, said hard plates and said soft members being alternately laminated with each other; said laminated body having one end portion in a laminating direction, said one end portion being connected to one of a vibration generation section and a vibration receiving section, and another end portion in the laminating direction, said another end portion being connected to the other of the vibration generation section and the vibration receiving section; wherein, among said plurality of soft members, a soft member that is arranged in a region, which is subjected to a higher isostatic pressure, is thicker than soft members that are arranged in other regions, wherein said one end portion of the laminated body in the laminating direction forms a fixed end that is fixedly connected to one of the vibration generation section and the vibration receiving section; said another end portion of the laminated body in the laminating direction forms a free end that is movably connected to the other of the vibration generation section and the vibration receiving section; and among said plurality of soft members, a soft member is softer in a region adjacent to the fixed end of the laminated body, than in other regions, and wherein, among said plurality of soft members, a soft member arranged closer to the fixed end of the laminated body has a thickness, which is within a range from 1.3 times to 1.7 times of a thickness of a soft member arranged closer to the free end of the laminated body.
