Influence of the Elastic Properties of the Spring Element on the Rotor Tuning Condition of a Rotor Vibratory Gyroscope

This paper considers the dependence of the rotor tuning condition of a rotor-vibratory gyroscope on the elastic properties of the spring element which has, in particular, additional angular deflection along an axis perpendicular to the output axis of gyroscope. As a consequence of this dependence, the limitations to the performance of the rotor tuning condition are examined and a mathematical equation describing the rotor tuning error, dependent on variations in the gyroscope parameters, is obtained. Analysis of the equation of rotor tuning error allows us to formulate the condition needed for minimization of this error against temperature change.
