<p><P>PROBLEM TO BE SOLVED: To provide a vibration control structure that can make a viscous elastic body effectively absorb vibration energy irrespective of a large vibration or a small vibration, and can sufficiently secure rigidity at the small vibration, and can increase a limit shearing deformation capacity of the viscous elastic body at the large vibration. <P>SOLUTION: Small vibration controlling viscous elastic bodies 4, 4 and a large vibration controlling viscous elastic body 3 are connected with each other with a first plate 1 and a second plate 2 set in parallel states, the small vibration controlling viscous elastic body 4 and the large vibration controlling viscous elastic body 3 are in a range of the limit shearing deformation capacity at the small vibration, at the same time, the large vibration controlling viscous elastic body 3 is in the range of the limit shearing deformation capacity in the large vibration, the small vibration controlling viscous elastic bodies 4, 4 are formed so as to exceed the limit shearing deformation capacity, and the connection of the first plate 1 and the second plate 2 by the small vibration controlling viscous elastic bodies 4, 4 is released at the large vibration. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
