摘　　要：该文构建了半球谐振陀螺(HRG)谐振子的静电驱动模型,对半球谐振子的1/2倍、1倍、2倍和更高阶频率电压信号的静电驱动力进行了理论推导分析。结果表明,该文得到的半球谐振子仅对其1/2倍、1倍及2倍谐振频率敏感,对其他频率信号不敏感。并推导出施加不同方式驱动电压信号力的大小,为半球谐振陀螺的驱动和闭环电路设计提供了依据。An electrostatic driving model of the resonator of hemispherical resonator gyroscopes(HRG)has been established in this paper.The electrostatic driving force of 1/2 times,1 times,2 times and higher frequency voltage signals of hemispherical harmonic oscillator is analyzed theoretically.The results show that the obtained hemispherical harmonic oscillator is only sensitive to 1/2 times,1 times and 2 times of the resonant frequency of hemispherical harmonic oscillator,and is not sensitive to other frequency signals.The magnitude of the force of the driving voltage signal applied in different ways is deduced,which provides a basis for the driving and closed-loop circuit design of the hemispherical resonant gyroscope.
