A B S T R A C T This article describes, develops and applies approach of the interaction of rough surfaces for one of the tasks of simulation of tribological systems of the piston engine. In this paper we described the general approach to building a model of interaction between rough surfaces, leading to the analysis of the Markov process. Given the initial data and the method of calculating the trajectory of movable elements on the lubricating layer,we determined the tribological parameters defining the service life of tribological systems of the piston engine on the example of crankshaft bearings.

Кроме того, дополнительно улучшить характеристики шатунного подшипника дизеля ДМ-21 удается подбором вязкостно-температурной характеристики применяемого масла (табл. 3).
