Abstract

The article discusses briefly the principles that can be used as a basis for the development of normative methods for the calculation and design 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; choice 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, friction and thermodynamic loads and operating in a corrosive medium, 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 also are used.

Keywords
