Title:
VIBRATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/062736
Kind Code:
A8
Abstract:
A vibration control device according to an embodiment of the present invention is configured such that, when a structure is deformed by applied external force, the vibration control device counterbalances the external force in response to deformation of the structure by the external force, thereby minimizing deformation of the structure by the external force. The vibration control device comprises: an external force transfer portion that is displaced in response to deformation of the structure by the external force while maintaining a contact with the structure; an external force attenuating portion connected to the external force transfer portion so as to attenuate the external force transferred from the external force transfer portion; and a mediating portion that mediates between the external force transfer portion and the external force attenuating portion while remaining fixed to the external force transfer portion. The external force attenuating portion comprises a rotating portion that makes a rotational movement according to displacement of the external force transfer portion and a slip portion that makes a linear movement while interworking with the rotating portion. The rotating portion can attenuate the external force through friction with the mediating portion following the rotational movement, and the slip portion can attenuate the external force through friction with the mediating portion following the linear movement.
