Title On the influence of the base vibration on the natural frequencies of a tuned rotor gyroscope

Abstract A one-ring tuned rotor gyroscope (TRG) placed on a moving base is considered. The base vibrates in accordance with a fairly generic law described, for example, by quasiperiodic functions.

Within the framework of the linear model, the motion of a TRG is governed by a system of differential equations with variable coefficients. This nonautonomous system of equations is reduced to an autonomous one with a prescribed accuracy by using a linear transformation [1]. For the latter system, we use the Rayleigh theorem generalized to gyroscopic systems [2] to analyze the evolution of the natural frequencies due to the base vibration.

The particular case where the base vibrates in accordance with a harmonic law was considered in [3]. The authors of that study analyzed the role of such vibration in the appearance of errors. Errors of TRG caused by various sources, including vibrational loads, were analyzed in detail in [4].
