摘要

Essential fabrication cost reduction saving high accuracy grade of HRG type instruments is an urgent task of Solid-State Gyroscopy [1], In report [2], principles of CRG-1 device developing by STM Co. (Ukraine) have been already considered. Instruments of this class use a novel type of shell resonators fabricated from a preform of profile high-Q single crystal, grown directly with the shape of the resonator. This technology excludes rough mechanical machining and, therefore, notable reduce cost of this class of sensors. In the present report, key design solutions of elastic decoupling of sensor and fixture have been considered that let us realize potentially high-Q of material itself (sapphire) in practice. Simulation by finite element method (FEM), using software like AnSys/NaSTRAN let us determine reasonable ratios of resonator's dimensions and evaluate real accuracy of classic cylindrical shell theory models.
