Item The simulation model of the trajectory of the point of contact of tool-workpiece during friction hardening(Lviv Polytechnic Publishing House, 2016) Dmyterko, Petro; Novitskyi, Yurii; Lviv Polytechnic National UniversityThe simulation model to simulate the trajectory of the precession motion of the point of contact with the toolworkpiece when there is direct and reverse the course of table machine during high-speed friction hardening is developed.Item Optimization of damping parameters of self-oscillations of multifrequency oscillatory system(Видавництво Львівської політехніки, 2017-12-23) Novitskyy, Yuriy; Dmyterko, Petro; Lviv Polytechnic National UniversityDeveloped and researched mathematical model four-mass scheme autoclave machine tools. Influence of parameters of internal friction is analysed in the joints of structural elements machine-tool on relative amplitude of vibrations the cutter and detail. The ambiguousness of influence of parameters of damping energy of vibrations is shown on relative amplitude of the vibrations a cutter and detail.Item Impact of processing modes and parameters of the working part of the instrument on the surface quality of flat parts during high-speed friction hardening(Видавництво Львівської політехніки, 2017-12-23) Dmyterko, Petro; Novitskyy, Yuriy; Gurey, Volodymyr; Lviv Polytechnic National UniversityImpact of processing modes and parameters of the working part of the tool-workpiece on the quality and surface precision of details during high-speed friction hardening of flat details is developed.Item Simulation model of dynamic processes during friction hardening of the flat surfaces(Lviv Polytechnic Publishing House, 2015) Gurey, Volodymyr; Dmyterko, Petro; Lviv Polytechnic National UniversitySimulation model of dynamic processes during frictional hardening the flat surfaces of assembly parts was developed.
