Bell-shaped vibrator type angular rate gyro

摘要

The present invention provides an angular rate gyro in which a bell-shaped vibrator having nonuniform thickness, axially symmetric and multi curved surface combined structural features is used as a sensitive element. The angular rate gyro is composed of the bell-shaped vibrator, a vibrator fixing shaft, a vibrator base, an airtight hood, a housing and a circuit system. The bell-shaped vibrator includes a bell shoulder having a hemispheric shell structure, a bell waist having a cylindrical shell structure and a bell lip having a hyperboloidal shell structure. The bell-shaped vibrator, the base and a central shaft are mechanically and fixedly connected together to be formed into an integral core having sensitive gyratory effect. A circuit system is used to control vibration forms of the bell-shaped vibrator, perform signal processing and solve the applied angular rate.
