Calculation of surface contact interaction in friction

The article briefly reviews analytical works on methods for calculating the parameters of contact interaction of rough surfaces. The influence of information technology development on scientific research and engineering problem solving is described. The contact of simulated surfaces is described. A number of assumptions are accepted and the principle of distribution of the protrusions of the rough surface is established. Further, the processes occurring during the contact interaction of rough surfaces in friction are described. Calculation relations are derived to determine the number of contact interactions between the protrusions of the surfaces under consideration. The volume of deformed material in the case of perfectly plastic deformation of its surface by absolutely rigid irregularities of the second surface is determined. The results of the work can be used for building calculation models of tribocouple wear and for the development of computer programs for modeling the processes of contact interaction of rough surfaces in friction.
