Abstract

The invention belongs to the field of sensors, and discloses an automatic vibrating gyroscope trimming method. The automatic vibrating gyroscope trimming method comprises the following steps: (1), automatically measuring the intrinsic frequencies of a harmonic vibrator of a vibrating gyroscope in two working modes, and calculating ta frequency cracking value according to the intrinsic frequencies;(2), if the frequency cracking value does not meet an accuracy requirement, comparing the two intrinsic frequencies to automatically determine a trimming mode and a corresponding trimming method; (3), controlling the gyroscope to move to an expected machining position by automatically positioning the relevant physical position of the gyroscope and the physical position of a trimming mechanism ofmachining equipment; (4), automatically planning a machining technology according to a relationship between the required removed mass and machining technological parameters, automatically trimming thegyroscope according to the planned machining technology, and returning to the step (1) after completion of trimming. By the method, the degree of automation is high and the trimming accuracy and thetrimming efficiency are improved.

Description

technical field [0001] The invention relates to a vibrating gyroscope, in particular to an automatic adjustment method for a vibrating gyroscope. Background technique [0002] With the continuous advancement of aerospace technology, applications such as high-resolution imaging, relay communication and navigation have higher and higher requirements on the attitude stability and life of satellites. As the core component of the satellite attitude control system, the gyroscope is used to measure the angular displacement and angular velocity of the satellite relative to the inertial space, and its zero bias stability is directly related to the satellite attitude stability. The on-orbit operation time of the satellite is more than 3 years or even 10 years. The gyroscope is a vulnerable part in the satellite, and its continuous working time is a key factor affecting the life of the satellite. The vibrating gyroscope is a solid wave gyroscope based on the principle of Coriolis forc...
