Nonlinear vibration and its influence on the vibratory cylinder gyroscope

Vibratory cylinder gyroscope (VCG) is an important type of vibratory gyroscopes with a lot of advantages. Manufacturing errors and material inhomogeneity are regarded as the main cause of the zero bias drift of the VCG. In this paper, the nonlinear vibration of the cylindrical resonator is considered. It is analyzed that the nonlinear vibration can cause extra drift of the VCG's output. Experiments are implemented in this research. According to the testing results, the metal cylindrical resonator is a soft nonlinear vibration system. To increase the stability of the VCG, the cylindrical resonator should be trimmed to a specific frequency split.
