Purpose. Investigation of the influence of parametric resonance in the zone of interaction of moving contacting surfaces on friction and wear when deformation-wave processes occur in front of a moving stamp. Metodology. To substantiate the reasons for the emergence of parametric oscillations on the contacting surfaces, a physical model has been proposed in which nonlinear dry friction between interacting parts is present, depending on the speed of their relative movement, which is the source of parametric (auto) oscillations in the area in front of the moving part. The techniques used to determine the length of the deformed part of the surface of the part, the number of half-waves on the site, as well as refined methods for calculating the heights of the deformation microroughnesses were used. Originality of the work lies in the fact that the reason for the intense wear of the interacting parts was revealed, which is the increase in the amplitudes of oscillations of the surface layers of the parts as a result of the manifestation of the parametric resonance effect. Practical value of the work is to achieve greater reliability in determining the deformation microroughness due to the use of a more accurate expression for the curvature of the bent beam axis, as well as taking into account the nonlinear relationships between the longitudinal and transverse deformations of the longitudinal axis of the hypothetical beam when it loses its longitudinal stability.
