Abstract

The invention provides a harmonic oscillator rigid shaft identification device and method based on an additional electrostatic rigidity principle. With the harmonic oscillator rigid shaft identification device and method adopted, the position of the rigid shaft of a harmonic oscillator can be accurately identified, so that the leveling effect of the harmonic oscillator can be ensured. The device comprises a rotary table, an electrode holder, comb-shaped electrodes, an electrode holder support mechanism, a signal source and a controller; the electrode holder is of an annular structure; the electrode holder is arranged above the rotary table; an harmonic oscillator supporting rod can penetrate through the electrode holder and is connected with a rotary shaft of the rotary table, so that the lip edge of the harmonic oscillator can be located above the comb-shaped electrodes; the comb-shaped electrodes comprise a comb-shaped direct-current excitation electrode, a comb-shaped alternating-current excitation electrode and a comb-shaped detection electrode which are distributed on the upper end face of the electrode holder in the circumferential direction, and are located bellow lip edge of the harmonic oscillator; the electrode holder support mechanism is arranged on one side of the rotary table and used for supporting the electrode holder; the signal source is connected with the comb-shaped direct-current excitation electrode; and the controller is connected with the comb-shaped alternating-current excitation electrode.

Description

technical field [0001] The invention relates to the technical field of hemispherical resonant gyroscopes, in particular to a device and method for identifying a rigid axis of a resonator based on the principle of additional electrostatic stiffness. Background technique [0002] Hemispherical resonant gyroscope (HRG) is a kind of vibrating gyroscope without high-speed rotor and movable support, which has the characteristics of high precision, small mass, small volume, short start-up time, high overload and high reliability. Known as the most potential Gothic vibrating top. The working principle of HRG is based on the Coriolis effect produced when the hemispherical shell harmonic oscillator rotates around the central axis, so that its mode shape precesses relative to the shell in the ring direction. [0003] When the harmonic oscillator is perfect and flawless, there is only one rigid axis when the harmonic oscillator works, and it has no directionality. It is only related to...
