dc.description Teza de doctor & Autoreferat en_US
dc.description.abstract Obiectivele lucrării sunt: studiul proceselor de durificare şi de netezire a suprafeţelor organelor de maşini, cunoscute şi aplicate în procesele industriale; stabilirea unei metodologii pentru realizarea simulărilor numerice ale proceselor tehnologice de prelucrare prin deformare plastică; Formularea modelelor de material; Validarea modelului de material folosit în operaţiunile de simulare a procesului tehnologic de deformare plastică la rece şi de netezire cu ecruisare; Experimentarea proceselor de durificare şi de netezire prin presare cu scule dure; Validarea experimentală a metodologiei de simulare numerică propusă şi aplicată în teza. en_US
dc.description.abstract The objections of the thesis are: studying the process of hardening and smoothing of the surfaces of machine parts, known and applied in industrial processes, developing a method for making a numerical simulation of the technological processes of treatment by plastic deformation, determination of the material’s properties, validation of the applied properties of the material for modeling the technological process of cold plastic deformation and smoothening with hardening. Experimenting the processes of hardening and smoothening by compressing with a hard tool. Experimental validation of the numerical simulating method proposed and applied in thesis. en
dc.description.abstract Задачами настоящей работы являются: исследование процессов упрочнения и выглаживания поверхностей деталей машин, известные и применяемые в промышленных процессах, разработка методики для проведения программного моделирования технологических процессов обработки пластическим деформированием, определение свойств материала, валидация использованных свойств материала для моделирования технологического процесса холодного пластического деформирования и выглаживания с упрочнением. Экспериментирование процессов упрочнения и выглаживания посредством сжатия твёрдым инструментом. Экспериментальная валидация методики моделирования предложенной и применённой в работе. ru
