description: The topic of the final qualifying work: "Regularities of the influence of temperature on the sliding friction of steel on thermoplastics". This work is devoted to the study of the effect of temperature on the friction of steel on thermoplastics in the mode of translational motion. Tasks that were solved during the study: - To conduct an analytical review of thermoplastics studies; - Select mathematical models to describe the external sliding friction of solids. - Implement the digitization of experimental data from well-known tribologists and analyze them using selected mathematical models to identify patterns of temperature influence on the sliding friction of steel on thermoplastics. The work was carried out on the basis of the BaltTribo-Polytechnic Research Center. Within the framework of this work, experimental data of well-known tribologists V. A. Mustafayev and Yu. Ya. Podolsky were analyzed. Test conditions: sliding of the steel hemisphere along the thermoplastics plane at a speed of 0.01 cm / s, at a load of 10 g in the process of gradual temperature increase.The samples are a ball made of steel grade SHX15, with a diameter of 12.7 mm, plates made of materials: low- and high-pressure polyethylene, polypropylene, polyformaldehyde, polymethylmethacrylate, polystyrene. Based on the conducted research, it was established: 1. The analysis of the experimental results shows the validity of the chosen mathematical model describing the dependence of the coefficient of friction on temperature during the frictional interaction of a steel ball with thermoplastics. 2. A number of new tribotechnical characteristics have been introduced in the developed mathematical model, which make it possible to characterize the frictional interaction in the metal-thermoplastics system in more detail. 3. The selected model describes both external and internal friction, while analyzing the intensity of changes in the coefficient of friction makes it possible to identify the conditions for changing the state of the thermoplastics during frictional interaction.
