description: The topic of the final qualifying work: "The laws of friction in a four-ball assembly in the presence of solid lubrication in vacuum conditions". This work is devoted to identifying the patterns of friction in a four-ball assembly in the presence of solid lubrication in vacuum conditions with temperature changes. Tasks that were solved during the study: 1) To select the components of the physical model to identify the patterns of friction in the four-ball assembly in the presence of solid lubrication in vacuum conditions with temperature changes. 2) Choose mathematical models to describe the external sliding friction of solids. 3) Implement the digitization of experimental data from well-known tribologists and analyze them using selected mathematical models to identify patterns of friction in a four-ball node in the presence of solid lubrication in vacuum conditions with temperature changes. 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 O. V. Lazovskaya and R. M. Matveevsky were analyzed. Test conditions: sliding of the steel ball on the three lower balls with a frequency of 0.3 rpm, at a load of 1.43 kGf, in the temperature range from 0 to 700 0C. Samples: 1) Balls made of steel WX15 (d=8mm); 2) Balls with three lubricating coatings.As a result of the work done: 1) The components of the physical model were selected to identify the patterns of friction in a four-ball assembly in the presence of solid lubrication in vacuum conditions with temperature changes. 2) A mathematical model has been chosen to describe the external sliding friction of solids. 3) The digitization of experimental data of well-known tribologists was implemented and their analysis was carried out using the selected mathematical model to identify the patterns of friction in a four-ball node in the presence of solid lubrication in vacuum conditions with temperature changes.
