FIELD: testing equipment.
SUBSTANCE: invention relates to methods of tribotechnical tests, in particular, to burn-in investigations. Substance: tribosystem is lubricated, friction is carried out, and it is loaded by a stepped external load to achievement of maximum loading capacity. The range of tribosystem loading is controlled by parameters of discrete and continuous acoustic emission in a certain range of frequencies, reflecting frequency and nature of capturing moments, and also variation of structural characteristics of friction surfaces in process of their burn-in. The main information parameters of the acoustic-emission signal are spectral density, amount of emissions and signal amplitude.
EFFECT: improved quality of tribosystem burn-in, increased accuracy and efficiency of feedback for maintenance of specified friction mode in process of burn-in.
