Goroshko // Proceedings of 4th International Conference On Design, Simulation, Manufacturing: the Innovation Exchange (DSMIE-2021), June 8-11, 2021, Lviv, Ukraine / Lecture Notes in Mechanical Engineering. Lviv, 2021.https://elar.khmnu.edu.ua/handle/123456789/11081This article describes mathematical models of stationary motion in rigid supports of a rigid rotor with a cylindrical chamber partially filled with fluid. It is considered limited from the above chamber, which is located eccentrically and symmetrically on the shaft. In each case, based on integrating the liquid equilibrium differential equations, the pressure distribution laws in the fluid and specific shapes of equal pressure surfaces are defined. Considered cases simulate fluid behavior in an auto-balancer without considering external damping. It is investigated that the fluid is symmetrical about the axis of rotation of the system. Simultaneously, its bulk is concentrated by eccentricity (with the eccentric arrangement of the chamber). The constructed models’ analysis shows the impracticability of automatically balancing the rigid rotor with fluid in the rigid supports. The experimental results confirm the assertion. These results are obtained using dynamic photography, which is realized on an up-to-date computer and video equipment.enRotorUnbalanced rotorRigid rotorOscillationsAutomatic balancingThe Auto-Balancing Unit (ABU)Стаття
