Splitting of Natural Frequencies of Cylindrical Resonator Gyro due to Non-Ideal Shape

The paper considers the research into splitting of natural frequencies of the cylindrical resonator gyro using the perturbation method. The resonator has minor nonaxisymmetric deviations from the ideal shape (minor non-circularity). A computation algorithm is designed for calculating the splitting of natural frequency of non-ideal resonator. Natural frequency splitting vs. geometric parameters diagrams are presented.
