英文摘要：

Through the study of the vibration characteristics and sensitive mechanism of Bell？shaped Vibratory Angu？lar Rate Gyro （BVG）, the BVG signal detecting method was obtained. First, the construction of a dynamic model of solids＇wave in a bell？shaped vibrator, under ideal conditions with three？dimensional method Ritz was designed. Next, the bell？shaped vibrator equivalent dynamic model with analysis method of similar systems was constructed. Next, the vibration characteristics of the vibrator＇s ring？shaped lip margin was studied, the signal generation mecha？nism was analyzed, and on this basis, the signal detection method utilizing multi？sensor fusion of capacitive sensor and piezoelectric sensor was proposed, theoretically verifying the reasonableness of the method. The proposed meth？od has reference value to the BVG＇s system design.
