Abstract
The results of the study of the influence of the harmonic components of non-circularity and non-cylindricity on the formation of the stress-strain state (SSS) of the surface layers of parts in interference fit joints are presented. It is determined, that in order to increase the reliability of fixed joints of parts in the shape errors of high-precision mounting surfaces, it is necessary to minimize the amplitudes of the harmonic components of the low-frequency range of the 2nd, 3rd and 4th orders and form an isotropic microrelief. Keywords interference fit joints, non-circularity of cross-sectional profiles, harmonic components, non-cylindricity, microtopography, microasperities, stress-strain state, shape deviation spectra. kaf-ts@stu.lipetsk.ru
