    Dynamic strength and stiffness assessment of circuit сards with respect to their geometric parameters
    (Хмельницький національний університет, 2021-10-12) Kovtun, Igor; Goroshko, Andrii; Petrashchuk, Svitlana
    Mathematical model for dynamic stress and deformation analysis in printed circuit boards and their dynamic strength and stiffness assessment has been designed with respect to geometric parameters of printed circuit boards and recommendations for their specification have been provided for engineering calculations, which ensure strength and stiffness of printed circuit boards subjected to dynamic forces. Comparative analysis of dependences obtained by mathematical modeling and MatLab simulation demonstrates similarity and negligible deviations in absolute values of obtained results and may be considered as verification for the mathematical model.

    Study on the Eccentric Rotor Dynamics in A Three-Phase Induction Motor with Squirrel Cage Rotor under Unbalanced Magnetic Field
    (Хмельницький : ХНУ, 2024) Goroshko, Andrii; Zembytska, Maryna
    This research investigates the behavior of a three-phase induction motor with a squirrel cage rotor under various eccentricity conditions. A mathematical model is developed to simulate the rotor's oscillatory motion, incorporating both mass eccentricity and magnetic forces. The model is then used to analyze the motor's vibrations in both time and frequency domains. Results show that static eccentricity causes vibrations at twice the electrical frequency, while dynamic eccentricity leads to a rotor frequency signal modulated by a lower frequency related to rotor precession. The developed model can be applied for diagnosing rotor eccentricity issues in induction motors.
