金属壳固体波动陀螺是基于固体波的进动效应进行角速度检测的一种全新轴对称壳振动陀螺,具有结构简单、功耗低、抗冲击性强、稳定性高等优点,可广泛应用于中低精度角速度测量领域。为分析轴对称多曲面融合结构金属谐振子中固体波的进动效应,在双曲率坐标系下,基于薄壳理论,建立了理想条件下轴对称多曲面融合结构金属谐振子中固体波进动的动力学模型。针对动力学模型过于复杂、难于分析的缺陷,提出了利用弹性力学中的能量原理,建立轴对称多曲面融合结构金属谐振子等效模型的方法,为金属壳固体波动陀螺的信号检测方法和控制回路设计奠定了理论依据。
The metal shell solid undulating gyroscope is a new axisymmetric shell vibrating gyroscope based on the precession effect of solid wave. It has the advantages of simple structure, low power consumption, strong impact resistance and high stability. It can be widely used in low and medium Accuracy angular velocity measurement field. In order to analyze the precession effect of the solid wave in the metal resonator with axisymmetric multi-surface fusion structure, the precession of solid wave in the metal resonator with axisymmetric multi-curve fusion structure under the ideal condition is established under the double curvature coordinate system. Kinetic model. Aiming at the defects that the dynamic model is too complicated and hard to be analyzed, a method of using the energy principle in elastic mechanics to establish the equivalent model of the metal resonator with axisymmetric multi-surface fusion is proposed. Circuit design has laid a theoretical basis.
