摘要
半球谐振陀螺是一种基于哥氏效应的固体波动陀螺,其具有高精度、长寿命、高可靠性的优势。频差直接影响着陀螺仪表的测量精度。针对存在主轴失准角的情况,建立了包含主轴失准角在内的完整电刚度补偿动力学模型,并给出了不同失准角度下的谐振子电刚度补偿方案及仿真结果。仿真结果表明,利用多电极组合补偿方法能够实现对主轴失准条件下的残余频差的完全抑制,为谐振子频差的电刚度补偿方法提供了借鉴。
The Hemispherical Resonance gyroscope(HRG)is a kind of solid wave gyro based on Coriolis effect.It has the characteristics of high precision,long life and high reliability.The frequency split determines the accuracy of the gyros directly.In the condition of princple-axis misalignment,the complete electric-stiffness compensation dynamic models is established and simulation results of different misalignment angles are given.The method achieves complete suppression of residual frequency difference.
