Varvarov V. Increasing the tribosystems resource in aggregation by switching them to abnormally low friction and wear

The dissertation deals with the actual scientific and practical problem of increasing the wear resistance (resource) of tribosystems in aggregation by transferring them to the mode of abnormally low friction and wear. The rheological construction of the surface layer of the TS under which conditions for the transition to abnormally low friction and wear (ALFW) is determined. A model of contact interaction of triboelements at the micro roughness level is developed, the role of surface roughness as a factor of self-regulation in changing external friction conditions is determined. The amplitude-frequency analysis of oscillations in the conditions of abnormally low friction and wear is carried out. The explanation of the transition of the vehicle from the ALFW to the negative friction at changing friction conditions and the analysis of the mechanism of destruction of surfaces at negative friction are recorded and given. Practical recommendations for the modification of the bronze elements of the steel-bronze tribosystems have been developed. The results of the work were introduced at PJSC "FED" in the manufacture of actuators-generators GP21KM aircraft of the family AN 148/158/178, whose resource increased more than 4 times.
