Title:
VIBRATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/097933
Kind Code:
A1
Abstract:
Provided is a vibration control device in which a vibration damping function effectively acts both when vibration displacement is large and when vibration displacement is small. This vibration control device 10 is provided on a structure 1 including a lower beam part 2 and an upper beam part 3. The vibration control device 10 is provided with a viscous damper 11, a friction damper 30, and a switching mechanism 40 that switches between vibration damping by only the viscous damper 11 and vibration damping by a combination of the viscous damper 11 and the friction damper 30. The switching mechanism 40 is provided with: first members 41 provided on a viscous fluid container 12; and second members 42 which are provided on a friction transmission plate 31 so as to face the horizontal movement direction of the first members 41, and which come into contact with the first members 41 when the horizontal displacement of the viscous fluid container 12 with respect to the friction transmission plate 31 exceeds a first predetermined gap L1, thereby moving the friction transmission plate 31 together with the viscous fluid container 12 in the horizontal direction.
