英文摘要：

Resonator is the core sensing cell of vibration gyro. Structure characteristics of resonator have decisive effect on the performances of vibratory gyro. The structure features and working principle of an axisymmetric thickness-variable resonator of vibration gyro are studied in this paper. The finite element model of the resonator is established. The effect of structural parameters on vibration characteristics of resonator are analyzed. On the basis of the theoretical analyses, a set of proper data for engineer design of resonator is presented.
