半球谐振陀螺的理论与实验研究

Theory and Experiment on Hemispherical Resonator Gyro

基于薄壳振动理论和半球壳谐振子的实际结构特征，研究了半球谐振陀螺的敏感元件即半球壳的振动特性。给出振子诺振频率和振型在环向进动的计算公式，并在所设计的半球壳样件上进行了相应的实验研究。理论计算与实验吻合。此外还给出了半球谐振陀螺闭环测量的结构图及检测原理。

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.
