Problems solved by technology

The traditional ordinary harmonic oscillator leveling is to remove a certain amount of vibrating part of the material at the edge of the harmonic oscillator. The smaller the material requirement, the more difficult the operation, the longer the adjustment time, and the lower the economy; and the balance method for the cup-shaped harmonic oscillator is still under study, and there is no relevant report

Abstract

The invention relates to a harmonic oscillator of a gyroscope and a balancing method thereof, in particular disclosing a cup-shaped harmonic oscillator of a cup-shaped fluctuated gyroscope and a mechanical balancing method. The cup-shaped harmonic oscillator comprises a side wall and a chassis fixedly connected to the bottom of the side wall, wherein the side wall comprises a harmonic oscillation ring at the upper part and an oscillation transfer part at the lower part, the center of the chassis is provided with an installation base, the top of the harmonic oscillation ring is uniformly distributed with modifying tanks are uniformly distributed on the top of the harmonic oscillation ring along a circumferential direction, and modifying holes are uniformly distributed on the chassis. The balancing method of the cup-shaped harmonic oscillator comprises the following steps of: firstly carrying out static balance regulation on the harmonic oscillator to make the mass center of the harmonic oscillator coincide with an ideal central shaft; then modifying the harmonic oscillation ring to reduce the frequency difference of the harmonic oscillator to an error range; modifying the chassis of the harmonic oscillator again to reduce the frequency difference of the harmonic oscillator to an expected value range; and finally modifying the chassis of the harmonic oscillator to make the oscillation mode of the harmonic oscillator consistent with the expected direction. The harmonic oscillator and the mechanical balancing method in the invention have the advantages of simple operation, convenient processing, high precision and efficiency, low cost and the like.

Description

technical field [0001] The invention relates to a harmonic oscillator of a gyroscope and a balancing method thereof, in particular to a harmonic oscillator of a solid wave gyroscope and a method for adjusting its resonance frequency and mode shape. Background technique [0002] The cup-shaped wave gyroscope is a new type of solid wave gyroscope, which uses the inertial effect of elastic waves in the cup-shaped structure to achieve angular velocity measurement. The cup-shaped wave gyroscope has the unique advantages of solid wave gyroscopes, such as high precision, low energy consumption, short preparation time, wide operating temperature range, strong resistance to ionizing radiation, good shock resistance and vibration resistance, and long service life. It has extremely broad development and application prospects. [0003] The working principle of the cup-shaped wave gyroscope is as follows: apply AC voltage to the four piezoelectric excitation electrodes perpendicular to e...
