SIMULATION OF THE PASSAGE OF HEAT FLOW THROUGH A FLAT JOINT Podkrugljak L.Y., Post-graduate Student, e-mail: podkruglak@mail.ru Samara State Technical University (Samara Polytech), 244 Molodogvardeyskaya st., Samara, 443100, Russian Federation Abstract Modeling the propagation of heat flows in the construction of a metal-cutting machine generate a need for taking into account in the thermal model the passage of heat flows from sources not only through solid parts, but also through the contacts of parts with each other. Since macro-deviations, undulation and roughness are present in real contacts, this leads to the appearance of contact thermal resistance (CTR), which must be taken into account in thermal models. The paper presents the initial data and a scheme for creating an experimental stand for measuring the temperature drop in a flat contact. To supplement field tests on an experimental stand, numerical simulation by the finite element method in the Workbench (WB) Ansys environment is proposed. The solution sequence is presented. A geometric finite element model is developed taking into account boundary conditions. The analysis of the calculation results is carried out, which on the one hand allow visualizing the thermal fields and deformations of the experimental setup under study, and on the other hand, it is in good agreement with the experimental data obtained during experiments on the developed stand. Keywords Finite element method, interdisciplinary analysis, temperature gradient, thermal deformations.
