摘要
圆柱壳体振动陀螺是一种重要的惯性导航传感器,有精度高、能耗低、耐冲击和寿命长等特点,具有广阔的应用空间。其性能与频率裂解、振型偏移、品质因数有关,它们直接影响陀螺的零偏稳定性。为了提高圆柱壳体振动陀螺的性能,机械修调十分必要。本文梳理了圆柱壳体振动陀螺修调的相关理论和近年来国内外有关陀螺修调的方法与装置,提出修调技术在未来可能的发展方向。
Cylindrical vibratory gyroscope is an important inertial navigation sensor, it has many advantages, such as high precision, low energy consumption, impact resistance and long lifetime, so it has a wide application space.Its performance is mainly related to parameters such as frequency split, vibration mode deviation and quality factor, which directly affect the zero bias stability of the gyroscope.In order to improve performance of cylindrical vibrating gyroscope, mechanical trim is necessary.Relevant theories of cylindrical vibratory gyroscope are reviewed and the methods and devices related to gyroscope trimming at home and abroad in recent years, and the possible future development direction of trimming technology is proposed.
