Title:
VIBRATION SHIELDING DEVICE AND EARTHQUAKE-RESISTANT POWER GENERATOR TO WHICH VIBRATION SHIELDING DEVICE IS APPLIED
Document Type and Number:
WIPO Patent Application WO/2016/013804
Kind Code:
A1
Abstract:
Provided are a vibration shielding device for shielding an object from the transfer of vibrations thereto, and an earthquake-resistant power generator to which the vibration shielding device is applied, and the vibration shielding device comprises: a box-shaped shielding case; a bed on which the object is mounted, and provided so as be movable in an inner space of the shielding case; a spring damper inserted between the shielding case and the bed; an actuator inserted between the shielding case and the bed so as to restrict the expansion and contraction of the spring damper with damping force varying according to the vibration of the shielding case; and a controller for controlling the actuator by outputting a signal for controlling the damping force of the actuator on the basis of the vibration of the shielding case.
