Twin resonance tuning-fork type gyro that is one of Vibratory Rate Gyroscopes has a number of advantages. On the other hand, its output signal is very small on the structure of the vibratory body as a fault. Therefore, the rate gyro of this type is supported by an elastic mechanism and is required high gain in the resonance between the excitation system and the detection system by fine tuning^<(7)>. However, the quick response and the stabilization of gyro vibration system worsen by high mechanical Q value. They are problems which do not coexist easily, and conflict. Then, it is necessary to give moderate damping to both of the twin resonance tuning-fork and the gyro support part for improvement of dynamic characteristics and stabilization. Therefore, this paper discribes an experimental study concerning the quick response and the stabilization of twin resonance tuning-fork type gyro made a high gain by the method of the first report, and reports on a method of obtaining moderate damping as the means.
