| Abstract: | Metal shell resonator gyroscope is a new type of shell vibrating gyroscope that uses the precession characteristics of standing waves to sensitively input angular rate. It has the advantages of simple structure, low power consumption, strong impact resistance and high stability. It can be widely used in the field of low and medium precision angular velocity measurement. Metal shell resonator gyroscope not only has the inertial quality of the traditional gyroscope, but also has the characteristics of being able to withstand high overload and large range, which is not available in other types of gyroscopes. Metal shell harmonic oscillator is the core part of the metal shell resonator gyroscope, and its performance is crucial. In this paper, the research progress of metal shell harmonic oscillator is reviewed in combination with metal shell resonator gyroscope. The design idea, theoretical modeling, structural design, signal processing and other aspects are discussed. The development trend of metal shell resonator gyroscope and its harmonic oscillator is pointed out. |
