MECHANICS OF FRICTIONAL CONTACT IN THE PLASTIC DEFORMATION RANGE
The topicality of researches devoted to interaction of surfaces in the process of friction on the small size of the ac-tual contact area is substantiated. That interaction occurs into tribomates of many machines, and mechanisms as well as in the process of technological running-in. In relation to the plain bearings by the method of slip lines is shown, that at plastic deformation of micro-roughness is convergence and overlap of the deformed parts under them. The modeling of real interaction by the introduction of the hard cone with a certain sizes into plastic half-space, subjected to one of the conditions of plasticity is considered. The basic equations from the results of ma-thematical modeling of interaction of rubbing surfaces, obtained on the basis of the fundamental assumptions of the theory of plasticity are presented. Evaluation of the results of mathematical modeling on the correspondence of the results of the experiments, established by the method of x-ray structural analysis is given. The analysis of the processes occurring in friction contact in a technological running-in of plain bearings is held. Calculated by establishing the conditions of plastic equilibrium of surface layer ranges of geometric and friction parameters of real contact, with which it is possible for the surface layer in the process of running-in.
