В работе методами численного моделирования проведена оценка тепловых деформаций рабочих элементов героторного винтового компрессора с внутренним зацеплением. Исследование основано на последовательном термоструктурном анализе в инженерном пакете ANSYS, включающем расчет стационарного температурного поля и последующее определение термоупругих деформаций. Установлено, что, несмотря на существенную величину тепловых деформаций, их согласованное направление приводит к незначительному результирующему изменению рабочих зазоров. На основе векторного анализа полей перемещений предложена методика назначения минимальных безопасных эксплуатационных зазоров. Разработанный подход позволяет численно оценить влияние тепловых деформаций рабочих органов компрессора при назначении минимально безопасных зазоров. </p></abstract><trans-abstract xml:lang="en"><p>One of the key tasks in the design of high-efficiency screw compressors is the reasonable assignment of working gaps, which are subject to significant thermal deformations under operating conditions. In the presented work, the thermal deformations of the working elements of a gerotor screw compressor with internal gearing are estimated using numerical modeling methods. The study is based on sequential thermal structural analysis in the ANSYS engineering package, which includes the calculation of a stationary temperature field and the subsequent determination of thermoelastic deformations. It is established that, despite the significant magnitude of thermal deformations, their consistent direction leads to a slight resulting change in the working gaps. Based on the vector analysis of displacement fields, a method for assigning minimum safe operational gaps is proposed. The developed approach makes it possible to optimize the design of gerotor compressors by assigning gaps without the risk of jamming, which leads to increased energy efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>героторный винтовой компрессор</kwd><kwd>тепловые деформации</kwd><kwd>роторы</kwd><kwd>внутреннее зацепление</kwd><kwd>зазоры</kwd><kwd>конечно-элементный анализ</kwd><kwd>ANSYS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gerotor screw compressor</kwd><kwd>thermal deformations</kwd><kwd>rotors</kwd><kwd>internal engagement</kwd><kwd>gaps</kwd><kwd>finite element analysis</kwd><kwd>ANSYS</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">Сакун И.
