DEMENT’EV, S.S. MAKAROV, M.YU. AL’ES The results of numerical simulation of changes in the parameters of axial and radial displacement in the processed metal billet made of 30HGSA steel from the thermoelastic deformation created by the calibrating tool during high-temperature thermomechanical processing are presented. Calculations of the model problem were carried out in the ANSYS program. An original numerical algorithm was used, built to solve deformation problems and integrated into the ANSYS program in the form of a calculation module. A qualitative and quantitative assessment of the design parameters of the radial and axial displacements occurring in the design nodes of the workpiece under consideration has been carried out according to two variants of the initial parameters of thermomechanical processing that take place in real production. A good agreement of the obtained values of the final diameters of the metal billet after thermomechanical processing according to the results of numerical modeling and the results of field experiments is shown. The given model makes it possible to predict changes in the allowance in the workpiece when obtaining the specified tolerances of the processed products in the real process of thermoelastic deformation during high-temperature thermomechanical processing.
