Совершенствование технологии изготовления гироскопических приборов, являющихся автономными датчиками выработки параметров движения объектов, имеет стратегическое значение и является приоритетным направлением развития различных отраслей промышленности. Объектом исследования выступают роторы шаровых гироскопов, геометрические параметры которых предопределяют точностные характеристики прибора. В работе представлены результаты моделирования процесса корректировки формы ротора на стадии его изготовления в процессе напыления функционального покрытия. Метод. Предложенная математическая модель процесса напыления основана на размещении между ротором и источником подвижного экрана с отверстием. Ось экрана лежит на динамической оси ротора и обеспечивает нанесение покрытия на поверхность сферического сегмента. Целью для разработки математической модели послужила необходимость управления геометрией напыляемой поверхности. Управление можно выполнить с помощью экрана с отверстием при использовании точечного источника напыляемого материала. Перемещение экрана или ротора вдоль динамической оси ротора в процессе нанесения дополнительного слоя, а также вращение ротора вокруг динамической оси позволяет в широких пределах и с высокой точностью до сотых долей микрометра регулировать кривизну формируемого покрытия. Основные результаты. Разработана аналитическая модель технологического процесса корректировки формы сферических роторов шаровых гироскопов. Приведено математическое описание, управляющие факторы и значимые параметры процесса. Представлены результаты практической апробации разработанных моделей. Обсуждение. Представленная математическая модель позволяет осуществлять корректировку формы роторов при напылении функционального покрытия, расширяя технологические возможности процесса изготовления и обеспечивая повышение точности роторов.</p></abstract><trans-abstract xml:lang="en"><p>Improvement of the manufacturing technology for gyroscopic devices, which autonomously generate motion parameters of moving objects, has strategic importance and priority for various industries. The object of current research is a spherical rotor of an electrostatically suspended gyroscope which geometric parameters determine the accuracy characteristics of the device. The paper presents results of the process modeling of spherical form correction for rotors of electrostatically suspended gyroscopes at the stage of its manufacture during the coating deposition process. The proposed mathematical model of the deposition process is based on the placement of a movable screen with a hole between a rotor and a spray source. The axis of the hole lies on the dynamic axis of the rotor and it provides a formation of a spherical segment on the coating rotor surface. During deposition of an additional layer, the screen or rotor moves along the dynamic axis of the rotor changing the distance between the rotor and the screen, and there is additional rotation of the rotor around its dynamic axis. It allows adjusting the curvature of the formed coating on the rotor surface. An analytical model of the technological process for correcting the shape of spherical rotors of electrostatically suspended gyroscopes has been developed. A mathematical description, control factors and signifcant parameters of the process are given. The results of practical testing of the developed model are presented. The presented mathematical model makes it possible to correct the shape of the rotors during the deposition of a functional coating expanding the technological possibilities and increasing the accuracy of rotors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>покрытие</kwd><kwd>корректировка формы</kwd><kwd>напыление</kwd><kwd>моделирование</kwd><kwd>сферический ротор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coating</kwd><kwd>shape correction</kwd><kwd>deposition</kwd><kwd>modeling</kwd><kwd>spherical rotor</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">Peshekhonov V.G.
