CALCULATION OF VIBRATING RING GYROSCOPE CHARACTERISTICS

There’re a short constructive description and a physical bases description of a vibrating ring gyroscope in this paper. Methods of all basic parameters calculation are showed. Also there’s a description of vibrating ring gyroscope dynamics in a steady-state mode and in transient mode. The relations between the damping parameter, the duration of transient, the steady-state value of deviation amplitude and the nonlinearity parameter are established on the basis of the modelling. Index Terms: micromechanics, angular rate, sensor, vibrating ring, gyroscope, solid-state wave, natural frequency, damping parameter, excitation, precession, kinematics, dynamics, nonlinearity, transient, steady-state value
