Aim of work - development of methods for parameters analysis of a rotary ground throwing mechanisms with blades of different shapes; creation of selection methods of basic parameters of oscillating technological devices; development of methods for stress-strain state analysis of the circle cylinders under the action of volume forces; post-impact and angular velocities calculations of the mass centers for particles; a solution method development for creep-damage problems of mechanical engineering designs. The results - - the search method of optimum shape of a curved blade profile is developed; the mathematical model of a soil particle movement on a rough curved blade is created; advantages of a curved optimum blade in comparison with a straight one by matching of parameters of soil particles descent are justified; strength test results for circular cylinders under the action of body forces are given; the some problems of particles motion of mixtures in the devices for their mixing and milling are considered; selection methods of basic parameters for oscillating technological devices are established; a numerical-analytical methods and software for long-term prediction of mechanical engineering designs at project stage are presented Product Description popup.authors Гранько Борис Федорович Дерев'янко Микола Іванович Ковревський Артур Петрович Соболь Володимир Миколайович Шатохін Володимир Михайлович popup.nrat_date 2020-04-02 Close
