Mathematical model of a dynamically tuned gyroscope (DTG) includes an elastic and not ideal ball bearings of the gyro spin motor. The DTG is considered as a mechanical system with eight degrees of freedom. Selection of the number of degrees of freedom is based on the gyroscope design features. The angular and linear displacements of the gyro spin shaft, suspension ring and rotor became possible due to deformation of ball bearings. This model is necessary for modeling the DTG dynamics caused by natural vibration of bearings, for calculation of natural frequencies and for considering the influence of particular defects of ball bearings on the gyroscope drifts.
