A hemispherical resonator mass balance processing device and working method

Abstract

The invention discloses a hemispherical resonator mass balance processing device and a working method. The mass balance processing device includes a shaft sleeve and a vessel, and one end of the shaft sleeve is used to connect with the handle end of the hemispherical resonator to be balanced. The other end of the bushing is connected to a rotating shaft, and the other end of the rotating shaft connected to the bushing is connected to the rotating shaft of the rotating motor. The handle end of the hemispherical resonator to be balanced, the bushing, and the The axes of the rotating shaft and the rotating shaft of the rotating motor are all located on the same extension line, and a lifting structure that can drive the entire mass balance processing device to rise or fall is also provided on the rotating shaft. Chemical etchant for etching the hemispherical resonator to be balanced. The solution can correct the geometric deviation of the hemispherical resonator, thereby reducing the inhomogeneity of its mass distribution.

Description

technical field [0001] The invention relates to the technical field of resonators, in particular to a hemispherical resonator mass balance processing device and a working method. Background technique [0002] As a new type of angle measurement sensor with high precision, high reliability and long life, hemispherical resonant gyroscope has been deeply concerned and systematically studied in the world in recent decades, and is widely used in aerospace and other fields. [0003] As the internal core component of the hemispherical resonant gyroscope, the hemispherical resonator is the carrier for sensing the external angle or angular velocity, and its accuracy will directly affect the measurement and navigation accuracy of the hemispherical resonant gyroscope sensor. The material of the resonator is usually fused silica with high Q value (quality factor), which will have more or less geometric deviation after being processed into a hemisphere, resulting in uneven mass distributi...

AI Technical Summary

Problems solved by technology

The material of the resonator is usually fused silica with a high Q value (quality factor). After it is processed into a hemisphere, there will be more or less geometric deviations, resulting in uneven mass distribution. This inhomogeneity will cause the resonator The resonant mode during operation produces frequency splitting, resulting in a large system drift of the hemispherical resonant gyroscope
