The paper presents the results of experimental and numerical studies of contact interaction of rubbing bodies after technological processing – discrete hardening. Experimental studies were carried out on the example of the contact pair "crankshaft of an internal combustion engine - liners". Numerical simulation was carried out using generalized parametric modeling of complex mechanical systems. To determine the stress-strain state of the elements being studied, the finite element method was chosen. Based on the results of the conducted studies, the efficiency of the proposed method of technological processing of contacting bodies – discrete hardening - was demonstrated.

W pracy przedstawiono wyniki eksperymentalnych i numerycznych badań kontaktu ciał trących po obróbce technologicznej - dyskretnym utwardzaniu. Badania eksperymentalne przeprowadzono na przykładzie pary kontaktowej "wał korbowy silnika spalinowego - wkładki". Symulacja numeryczna została przeprowadzona przy użyciu uogólnionego parametrycznego modelowania złożonych układów mechanicznych. Aby określić stan naprężenie-odkształcenie badanych elementów, wybrano metodę elementów skończonych. Na podstawie wyników przeprowadzonych badań wykazano skuteczność proponowanej metody technologicznej obróbki ciał stykowych - dyskretne utwardzanie.
