Несмотря на большой опыт традиционных методов изготовления, включающих в себя лазерную сварку, переход к использованию технологии аддитивного производства дает значительные преимущества: получение конструкции закрытого рабочего колеса как единой детали, где нет никаких соединений и мала вероятность наличия дефектов. Рассмотрено напряженное и деформированное состояние закрытого рабочего колеса центробежного компрессора при высоком числе оборотов (60400 об/мин). Для прочностного расчета рабочего колеса была построена трехмерная модель и выполнен прочностной анализ. Расчеты выполнялись в пакете ANSYS Workbench 2019. В результате расчетов было определено расположение области максимальной концентрации напряжений. Указанные области расположены на расстоянии 30…40% длины лопаток и в области входных кромок сплитеров. В областях концентрации напряжений учитывалась пластичность материала колеса. Были заданы основные механические свойства аддитивных материалов, используемых для рабочего колеса — нержавеющей стали марки 316, алюминиевого сплава AlSi10Mg, титанового сплава Ti-6Al-4V, мартенситной стали 17-4PH. Выполненные расчеты показали, что титановой сплав Ti-6Al-4V наилучшим образом удовлетворяет как прочностным, так и технологическим требованиям. Проведенный анализ позволил подобрать материал для вращающихся компонентов высокооборотной турбомашины.</p></abstract><trans-abstract xml:lang="en"><p>The traditional manufacturing process for shrouded impellers in centrifugal compressors is characterized as a multi-stage process, which involves attaching blades to the impeller and welding a cover disk to the blades. Despite the extensive experience gained with traditional manufacturing methods, including laser welding, transitioning to additive manufacturing technology offers significant advantages: it enables the production of a shrouded impeller as a single, seamless part with no joints, thereby reducing the likelihood of defects. This article examines the stress and deformation behavior of a shrouded impeller in a centrifugal compressor operating at high rotational speeds (60400 rpm). A three-dimensional model was created, and a strength analysis was conducted to evaluate the structural integrity of the impeller. The calculations were performed using the ANSYS Workbench 2019 software. The results identified the locations of maximum stress concentration, which occur at 30 – 40% of the main blade length and near the leading edges of the splitters. In these regions of stress concentration, the ductility of the impeller material was considered. The primary mechanical properties of the additive materials used for the impeller — stainless steel grade 316, aluminum alloy AlSi10Mg, titanium alloy Ti-6Al-4V, and martensitic steel 17-4PH — were specified. The analysis showed that the titanium alloy Ti-6Al-4V best satisfies both the strength and technological requirements.The conducted analysis facilitated the selection of a suitable material for the rotating components of high-speed turbomachinery.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конструкционная прочность</kwd><kwd>закрытое рабочее колесо</kwd><kwd>центробежный компрессор</kwd><kwd>аддитивные материалы</kwd><kwd>высокоскоростные турбомашины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>structural strength</kwd><kwd>shrouded impeller</kwd><kwd>centrifugal compressor</kwd><kwd>additive materials</kwd><kwd>high-speed turbomachinery</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Robust Operational Optimization of a typical micro Gas Turbine.
