Mass balance processing device for hemispherical resonator and working method

Abstract

The invention discloses a mass balance processing device for a hemispherical resonator and a working method. The mass balance processing device comprises a shaft sleeve and a vessel; one end of the shaft sleeve is connected with a shaft handle end of a hemispherical resonator to be subjected to balance processing, and the other end of the shaft sleeve is connected with a rotation shaft; the otherend, connected with the shaft sleeve, of the rotation shaft is connected with a rotating shaft of a rotation motor; the shaft handle end of the hemispherical resonator to be subjected to balance processing, the shaft sleeve, the axis of the rotation shaft and the axis of the rotating shaft of the rotation motor are located on the same extension line; a lifting structure capable of driving the whole mass balance processing device to ascend or descend is arranged on the rotation shaft; and chemical corrosive liquid capable of corroding the hemispherical resonator to be subjected to balance treatment is placed in the vessel. According to the technical schemes of the invention, the geometric deviation of the hemispherical resonator can be corrected, so that the nonuniformity of mass distribution of the hemispherical resonator is reduced.

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 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 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. Th...

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
