    Investigation of Small Motions of Liquid in Cylindrical Chamber of Auto-Balancing Device
    (Kaunas University of Technology, 2018) Drach, I.; Bubulis, А.; Mažeika, D.; Kandrotaitė Janutienė, R.; Juodvalkis, D.
    The article deals with the process of wave form-ing on the surface of a liquid in a chamber of a liquid auto-balancing device partially filled with a liquid for rotors with a vertical axis of rotation under non-stationary modes of the system's motion. In non-stationary processes, the possible wave formation causes a dynamic instability in the operation of the machine and the increase of vibrations under certain operating modes. In the article the problem for the case when the rotor is installed in elastic supports is solved, the joint movements of the rotor - liquid system are considered and their stability is investigated.

    Movement of Working Fluid in the Field of Centrifugal Forces and Forces of Weight
    (Kaunas University of Technology, 2016) Drach, I.; Royzman, V.; Bubulis, А.
    The article deals with the influence of gravity to work of fluid auto -balancing units (ABUs) of direct ac-tion. The movement of fluid in the chamber of ABU for rotors with a horizontal axis of rotation is considered. The influence of damping resistance to fluid movement in the cylindrical chamber is shown. Fluid flow with regard to the camera angle of inclination relative to the horizon is ana-lyzed. To analyze the movements of the working fluid in the field of centrifugal force and gravity forces mathemati-cal tools of parametric oscillation is applied.
