Damping device and vibration control apparatus for structure
A device for damping a transmitted vibration by the moment of inertia of a fly wheel and the adjustable resistance force of a viscous magnetic fluid to allow the viscous magnetic fluid exerts its property even under no external power source. A sleeve with an attached ball nut is disposed in a first cylinder so as to reciprocate. The reciprocating motion of the sleeve is converted into a rotational motion by a ball screw to rotate a fly wheel in a second cylinder and a generator rotating shaft. Between the fly wheel and the inner surface of the second cylinder, a sealed space is formed in which a viscous magnetic fluid is sealed. A magnetic field generating unit which generates a magnetic field running across the sealed space with the fly wheel serving as a part of a magnetic circuit is disposed on the inner circumference of the second cylinder.
