Abstract

A hemispherical resonator gyroscope is a high-precision solid-state gyroscope that utilizes the standing wave vibration characteristics of a hemispherical resonator to detect angular motion. The core assembly process of a hemispherical resonator gyroscope mainly involves the precise assembly of a hemispherical resonator and a flat electrode. The assembly structure essentially constitutes a capacitor system, and its performance is related to parameters such as assembly tilt, assembly eccentricity, and average assembly clearance. By establishing a comprehensive model that includes static and dynamic capacitance characteristics, the influence of the above parameters on the excitation efficiency of the resonant standing wave is studied. Assembly errors can lead to non-uniform distribution of signal gains in various detection channels, and this gain difference can cause calculation errors in standing wave azimuth and distribution deviations in control vector. These errors can lead to drift errors in the gyroscope system, ultimately constraining the overall performance of the gyroscope.
