Example Embodiment

[0025] The invention carries out structural design for the direct output frequency resonant gyroscope, and realizes the gyroscope sample by adopting new technology and new structure. A frequency output gyroscope research model designed by the invention includes a signal excitation unit, a magnetostrictive actuator, a resonator and a signal detection unit. The signal excitation unit adopts mature digital control technology. The required excitation signal is calculated by the controller, and then the analog signal is output through the signal generator, and then the drive signal output is realized through the power amplifier. The tuning fork excitation adopts a widely recognized piezoelectric film Excitation / pick-up mode, self-excited drive is realized through closed-loop technology, these two technologies will not be repeated here.

[0026] Such as figure 1 , figure 2 As shown, a direct output frequency resonant gyro research system includes a signal excitation unit 1, a magnet...

Abstract

The invention discloses a research system for a resonant gyroscope capable of directly outputting frequency. The research system is mainly applied to the theoretical and experimental research of a resonant gyroscope capable of directly outputting frequency. The research system comprises a magnetostriction actuator, a harmonic oscillator, a signal excitation unit and a signal detection unit, wherein the signal excitation unit generates a sine-wave drive signal according to a mechanical characteristic of a resonant gyroscope mass block under the action of coriolis force to act on the magnetostriction actuator, so that the magnetostriction actuator applies alternating sine force in the axial direction and acts on the movable end of the harmonic oscillator, the inherent resonant frequency of the harmonic oscillator is also changed, the principle and function verification of the resonant gyroscope capable of directly outputting frequency is realized, the work characteristics of the gyroscope under conditions of different structural models and different resonant oscillators as well as at different input angular rates can be simulated by changing output signals of a drive unit, non-linear dynamic feature of the gyroscope during inputting of non-linear signals is obtained by inputting non-linear drive signals, and an effective research method and an experimental platform are provided for non-linear research of the gyroscope.

Description

technical field [0001] The invention relates to a direct output frequency resonant gyroscope research system, which belongs to the field of theoretical research and experimental verification of the direct output frequency resonant gyroscope. Background technique [0002] A gyroscope is a device that measures rotational angular velocity or angular displacement in inertial space. It has an extremely important position in the field of science and technology today, and plays an important role in the development of the national economy and the modernization of national defense. The level of gyroscope technology and application largely reflects the level of information technology, and also affects the development and progress of science and technology. [0003] For resonant gyroscopes, the earliest and simplest structural form is the Foucault pendulum. In order to prove that the earth is rotating, Foucault conducted a successful compound periodic oscillation experiment in the ha...
