【Abstract】 On the basis of the thin shell’s vibration theory and actual feature of the hemispherical shell resonator. The vibrating characteristics of the hemispherical shell or the sensing component of the hemispherical resonator gyro were studied. The formulas for finding the resonant frequency and the precession of the vibrating shape in circumferential direction were presented, and the corresponding experiments were carried out on a test sample which is designed by us. And the experimentations agree with the calculations. Moreover, the closed loop measurement scheme and detecting principle of hemispherical resonator gyro were provided.更多还原
