Abstract
The approach to forecasting accelerated modes for faster testing of friction pairs having solid lubricant coatings using computer simulation is examined. Load and temperature test modes under which acceleration leads to faster testing were defined. Loads and temperatures have been revealed that determine the multiple transition from predominantly elastic and elastoplastic deformation of solid lubricant coatings to a predominantly elastoplastic and plastic one, which characterizes the maximum performance of high-resource friction pairs with solid lubricant coatings. Comparison of the results of the full-scale experiment and numerical experiments confirmed the correctness of the proposed method. It is shown that the ratio of elastoplastic contacting to all contacting protrusions determines the conditions under which the forcing of the modes leads to accelerated testing.
