Consideration on equivalent mechanical circuits for vibratory gyroscope

Equivalent circuits for vibratory gyroscopes used as angular rate sensors are considered. The equations of gyro-motion for a vibratory gyroscope using the flexural double resonator are considered via the normal mode function. Equivalent circuits for vibratory gyroscopes with different vibrating forms are proposed. A novel vibratory gyroscope using rotating motion in a double resonant vibrator is studied by the equations of gyro-motion based on a mechanical model. The principle of this gyroscope is indicated and the construction is shown
