Abstract The article gives the description of the calculation and experimental assessment of the durability and other characteristics of the resistance to wear-and-fatigue damage to a “shaft – liner” active system under regular and irregular loading for mechano-sliding fatigue, developed on the basis of the energy criterion of limiting states. The methodology is based on the nonlinear hypothesis of the wear-and-fatigue damage accumulation, takes into account the influence of different in nature hardening-softening processes associated with the class of material (cyclically hardening, softening, or stable), the nature of irregular loading, the properties of a corrosive environment and other factors. An algorithm for calculating the durability, taking into account the loading history, is developed. An example of calculation is considered. The curves of sliding and mechano-sliding fatigue of the active system “shaft (0.45 % carbon steel) – liner (siluminum)” are constructed.
