description: The subject of the graduate qualification work is Â«Modeling and research of frictional interaction of friction pairs "wheel-rail", "wheel-brake block" when the train is movingÂ». This given work is devoted to modeling and researching ways to improve the performance of friction pairs "wheel-brake block", "wheel-rail" by applying the "Ferstrong" coating. Tasks that were solved in the course of the study: 1. Using ProeENGINEER to model the wheel-brake shoe and wheel-rail friction pairs, and then using the ABAQUS CAE finite element analysis program, simulate the movement of a heavy-duty railway freight train moving at a speed of 80 km/h . Calculate the thermal field of the tread and the field of thermal stresses in the wheel of a railway train during braking. 2. On the SMTs-2 friction machine, carry out tribotechnical tests of the friction of the wheel on the rail under conditions of 10% slip, with and without the addition of lubricant, on samples with a "Ferstrong" polymer coating, followed by an assessment of wear and metallographic observations. 3. Conduct a study of the surface roughness of the samples before and after tribological tests with 10% slip. The work was carried out at the International Scientific and Educational Center of the International Scientific and Educational Center "BaltTribo-Polytechnic", where a significant part of the factual material was collected: modeling and calculation of friction pairs "wheel-brake shoe" and "wheel-rail", the results of tribotechnical tests, metallographic analysis of samples.
