“…It is proposed in [7,8] to reduce the aerodynamic and usual unbalances before the beginning of the operation of the fan. For this, first the aerodynamic unbalance is reduced by correction of the shape of the impeller blade [7].…”

“…It is considered in [8,9] that mass correction acts at certain rotation velocity, that is, with a decrease or increase of velocity, the balancing is broken. Therefore, for pass-balancing of unbalanced variables, passive auto-balancers are used in the fan operation [9].…”

“…The usual and aerodynamic unbalances are the main sources of vibrations of such machines [2][3][4][5][6]. They are balanced both before the operation of the fan and during its operation [7][8][9]. There are known methods of the static and dynamic pre-balancing of fans, and their effectiveness is also determined [10,11].…”

Експериментально досліджено процес статичного і динамічного балансування кульовими автобалансирами крильчат-ки осьового вентилятора. Вивчено вплив автобалансирів на ділянці розбігу та вибігу вентилятора, а також ефектив-ність роботи автобалансирів на ділян-ці крейсерського руху. Встановлено, що: наявність автобалансирів не погіршує вібраційний стан вентилятора на ділянці розбігу та покращує його на ділянці вибі-гу; на ділянці крейсерського руху доцільно застосовувати два автобалансири Ключові слова: осьовий вентилятор, аеродинамічна незрівноваженість, вібро-пришвидчення, автобалансир, динамічне балансування, перехідні процеси Экспериментально исследован про-цесс статической и динамической ба-лансировки шаровыми автобалансира-ми крыльчатки осевого вентилятора. Изучено влияние автобалансиров на участках разгона и выбега вентиля-тора, а также эффективность рабо-ты автобалансиров на участке крей-серского движения. Установлено, что: наличие автобалансиров не ухудшает вибрационное состояние вентилятора на участке разгона и улучшает его на участке выбега; на участке крейсерско-го движения целесообразно использо-вать два автобалансира Ключевые слова: осевой вентиля-тор, аэродинамическая неуравновешен-ность, виброускорение, автобалансир, динамическая балансировка, переход-ные процессы

“…For example, Kim et al [14] optimized the aerodynamic and aeroacoustic performance of an axial-flow fan using a NSGA-II algorithm combined with a surrogate model based on three-dimensional unsteady RANS (Reynolds-averaged Navier-Stokes) and Ffowcs Williams-Hawkings equations. To improve the multiple aerodynamic performance of an axial compressor, Wang et al [15] applied a multiple genetic algorithm combined with NSGA-II and a neural network model.…”

A multidisciplinary optimization was conducted to simultaneously improve the efficiency and reduce the radial force of a single-channel pump for wastewater treatment. A hybrid multi-objective evolutionary algorithm was coupled with a surrogate model to optimize the geometry of the single-channel pump volute. Steady and unsteady Reynolds-averaged Navier-Stokes equations with a shear stress transport turbulence model were discretized using finite volume approximations and were then solved on tetrahedral grids to analyze the flow in the single-channel pump. The three objective functions represented the total efficiency, the sweep area of the radial force during one revolution, and the distance of the mass center of sweep area from the origin while the two design variables were related to the cross-sectional area of the internal flow of the volute. Latin hypercube sampling was employed to generate twelve design points within the design space, and response surface approximation models were constructed as surrogate models for the objectives based on the values of the objective function at the given design points. A fast non-dominated sorting genetic algorithm for local search was coupled with the surrogate models to determine the global Pareto-optimal solutions. The trade-off between the objectives was determined and was described in terms of the Pareto-optimal solutions. The results of the multi-objective optimization showed that the optimum design simultaneously improved the efficiency and reduced the radial force relative to those of the reference design.
