Document Type and Number:
Japanese Patent JP2814241
Kind Code:
B2
Abstract:
A vibration control system for damping vibration of a body to be isolated against vibration, wherein the body (1) is supported on a movable base (3) through the medium of vibration damping supporting structure (2). The control system comprises a vibration sensor (4) for detecting vibration of the movable base (3), an inverse vibration signal generating circuit (20) including a digital sensor and supplied with a detection signal outputted from the vibration sensor (4) for generating a vibration signal of such a waveform to cancel out the vibration of the body through interference therewith, and an actuator (12) connected operatively to the movable base and the inverse vibration signal generating circuit for converting the vibration signal derived from the latter into a mechanical vibration to be applied to the body for thereby decreasing the vibration thereof.
