  • Vibration isolation system
    Patent number: 4405101
    Abstract: A vibration isolation system in which a supported body is supported from a vibration excitation body which is prone to vibrate at a predominant frequency and to impart such vibratory forces and motions to the supported body. The isolation system is of the antiresonant type and operable to provide vibration force and motion isolation of the supported body from the vibration excitation body both axially along and rotationally about three mutually perpendicular axes, thereby giving the supported body six degrees of vibration isolation from the vibration excitation body.
