Calculations of the values of amplitudes and initial phases for ten component harmonics (from the 1st to the 10th), the dispersion of deviations from roundness, as well as the specific weight of each harmonic in the resulting dispersion ( ) k D A were carried out according to the developed program using computer technology. Spectra of the amplitudes of deviations from the roundness the rolling bushings ICS are shown in Fig. 2.
