Title:
VIBRATION ISOLATION DEVICE
Document Type and Number:
Japanese Patent JP2576691
Kind Code:
B2
Abstract:
PURPOSE: To prevent vibrations generated by an apparatus mounted on an artificial satellite from being transmitted to the body of the satellite and also prevent vibratory transmission in the opposite direction.
CONSTITUTION: A vibration isolating device is composed of a stator housing 1 fixed to the body of an artificial satellite and having a stator cylinder, a rotor housing 5 fitted in the stator cylinder and supporting an apparatus concerned, a piezo element driver 3 placed in the stator cylinder 1 in such a condition that one end is in contact with the stator housing 1 and the other end in contact with the rotor housing 5, a preload bolt 4 which is installed between the rotor housing 5 and stator housing 1 and gives an initial compression force to the piezo element driver 3, and a displacement sensor 7 which is secured to the rotor housing 5 and measures the displacement of the rotor housing 5 relative to the stator housing 1. The piezo element driver 3 is operated so that the displacement given by the displacement sensor 7 nullifies.
