Fused quartz imperfections and their influence on the CVG resonator dynamics

Abstract

The paper presents the engineering estimate of the dispersion level of the values of such fused quartz glass physical and mechanical properties as density and elasticity modulus. The value scatter of the considered parameters over material volume leads to  negative effect appearance —  working natural frequency splitting of gyroscope resonator. Evaluation is carried out on the basis of the consideration of the fused quartz glass micro-structure and variability of its parameters. As a result, resonator frequency splitting values from calculated scattering levels of the structural material properties are presented.
