High quality cylindrical resonators are extremely important to guarantee the performance of cylindrical vibratory gyroscope. Cylindrical resonators’ damping asymmetry is one of the major sources which result in the gyroscope’s drift. In this paper, the method of evaluating damping asymmetry based on the Q factors of the damping axes is proposed. The dynamic model of cylindrical resonators is established...
Damping asymmetry is one of the major sources which result in the gyroscope's drift. In this paper, the method of evaluating damping asymmetry by the Q factor circumferential distribution is proposed. The dynamic model of cylindrical resonator is established to analyze the Q factor circumferential distribution based on the amplitude-frequency response (AFR) analysis. Theoretical results shows that...
