Институт физико-техничеcких интеллектуальных систем
Институт физико-технических интеллектуальных систем впервые в стране обеспечивает комплексную подготовку специалистов по созданию киберфизических устройств и систем самого различного назначения – основного вида технических устройств середины 21 века. ИФТИС реализует «дуальную» модель образования, в рамках которой направляет студентов на стажировку и выпускников для трудоустройства на передовые предприятия, занятые созданием инновационных киберфизических продуктов, в первую очередь, на предприятия ГК «Росатом». Основным индустриальным партнером ИФТИС является ведущее предприятие ГК «Росатом» — ФГУП «ВНИИА им. Н.Л. Духова».

- ПубликацияТолько метаданныеThermal phenomena and dynamic features of deep holes fabrication for connections of heat exchange tubes(2019) Terekhov, V.; Smirnov, A.; Mironova, L.; Терехов, Виктор Михайлович; Миронова, Любовь ИвановнаDeep drilling process has been studied and properties of dynamic interaction revealed between the cutting part of the gun drill with the machined surface of the hole. It was found, that the oscillations cause lesser precision and poorer quality of the hole surface. Thermal processes of cutting and heat sinking in the interacting chains were analyzed. These theoretical estimates show influence of the heat flux pulsations onto friction coefficients and cutting force. Mathematical dependence of the longitudinal and torsional oscillations of the cutting drill bit versus the above factors was defined. (C) 2019 Elsevier Ltd. All rights reserved.
- ПубликацияТолько метаданныеQuestion of creation of general theory of deep holes machining(2019) Kondratenko, L.; Mironova, L.; Terekhov, V.; Миронова, Любовь Ивановна; Терехов, Виктор Михайлович© 2019, Springer Nature Switzerland AG. The article notes that the development of industry poses the task of creating a general theory of the deep hole machining in the details. It is shown that drilling holes in details largely depends on the dynamic features of the mechanisms and the cutting process. A system of differential equations describing only the longitudinal and torsional oscillations of the cutting part of the tool is given. Using the example of the experiment on drilling holes with a diameter of 16 mm in austenitic, pearlitic steels, the problems associated with the construction of the cutting part of a gun drill, its wear, and the dynamics of the cutting process are shown. In a simplified setting, some features of the hydraulic system of the whole deep drilling machine are described, taking into account the supply of cutting fluid.

- ПубликацияТолько метаданныеOn Issue of Verifying New Method for Studying Dynamics of Deep Hole Machining(2020) Kondratenko, L.; Mironova, L.; Terekhov, V.; Миронова, Любовь Ивановна; Терехов, Виктор Михайлович© 2020, Springer Nature Switzerland AG.The article outlines the principles for constructing a mathematical model for the study of dynamic phenomena of deep holes machining. A theoretical justification is given for using the differential equation of the angular momentum for torsional vibrations. A solution of a second-order partial differential equation using the Laplace integral transform method is presented. Two ordinary differential equations are introduced, which sufficiently describe the relationship between the angular acceleration and the gradient of the change in tangential stress in the rod and the rate of change in voltage with the gradient of the angular velocity of motion. These equations allow us to calculate the frequency characteristics of the drive as applied to the technology of deep hole machining using the boring and trepanning association (BTA) method. The correctness of the mathematical formulations of the new research method is justified by the verification of the solutions obtained using classical calculation methods and models.
