The paper objective is to solve the issues related to the increase of reliability, profitability, and safety of modern washing ma-chines on the basis of decrease in dynamic loads under whizzing. The principles of forming operation factors in the liquid self-balancing device (SBD) with the displaced fluid (on which de-sign a number of patents are received) when passing a resonance zone under whizzing are considered. A comparative analysis of the SBD function implementation for the conditions of forming an adequate force response to the force input for two earlier es-tablished most rational conditions: for the force generated by resonance, and if reached the maximum unbalanced force, is carried out. The dependences of the SBD internal capacity trav-erse on the design factors of the SBD and the cleaning unit sus-pension system, and also on the operation parameters of the ex-traction process, are obtained. The research results are submitted in diagrams. The results analysis allows drawing the conclusions on the obtained data application perspectiveness to ensure maxi-mum efficiency of the process of balancing irregular masses of textiles in the drum during the whizzing cycle.

В настоящее время снижение виброактивности при центробежном отжиме является одним из при-оритетных вопросов, стоящих перед разработчиками стиральных машин барабанного типа. Актуальность данной про-блемы обусловлена необходимостью обеспечения более высоких показателей надежности, безопасности и экономич-ности стиральных машин, а также снижения вредного воздействия вибрации и шума на человека.
Эффективным направлением снижения виброактивности стиральных машин является использование жид-костных автобалансирующих устройств (АБУ) — в частности, АБУ с вытесняемой жидкостью [1–4].
Вопросам исследования жидкостных АБУ, применяемых в стиральных машинах, посвящен ряд научных пуб-ликаций. При этом исследователи отмечают недостаточность имеющейся в настоящее время информации о дисба-лансных характеристиках отклика системы и стабильности работы устройства [5, 6].
