Abstract:At present, the assembly process of the hemispherical resonant gyroscope(HRG) has problems such as low assembly accuracy, poor consistency and low yield. The shortcoming of the hemispherical resonant gyroscope assembly technology is one of the main reasons that restrict its performance index improvement, high qualification rate and mass production. First, it summarizes the research status of hemispherical resonant gyroscope products, summarizes the key technology of hemispherical resonant gyroscope assembly, and explains the urgent need to break through the assembly-oriented geometric error modeling technology, non-destructive flexible clamping technology, indium key technologies such as welding connection process and precision detection technology of non-parallel plate capacitance. And finally analyze the development trend of hemispherical resonant gyroscope assembly technology.
