The paper briefly discusses the principles that can be used as a basis for the development of statutory methods for calculating and skateboards designing of tribo-fatigue systems.The implementation of such principles is illustrated by the solution of the following main tasks: determination of the required dimensions of the elements of the tribo-fatigue systems and the area of their contact; selection of materials for their manufacture; determination of the required value of the coefficient of friction to ensure a given operational reliability of the system; forecasting of durability and reliability by the criteria of tribo-fatigue, determination of wear intensity and wear resistance group; risk (safety) of operation assessment.The formulas obtained in the framework of the generalized energy theory of the limiting states of tribo-fatigue systems under the influence of volume, Miniatures Kit friction and thermodynamic loads and operating in a corrosive medium, as well as theory of reliability for such systems by the criteria of fatigue resistance, vibration, wear and erosion resistance, the concept of L-risk and Sρ-safety are used.
