Для прогнозирования возможных нагрузок на конструкции из композитов и учета этих данных на начальном этапе разработки деталей требуется произвести компьютерное моделирование процессов, связанных с ними. Предложен бессеточный метод оптимизации изделий из композитных материалов на основе эластично связанных метачастиц. Получены результаты оптимизационных расчетов размеров для тестовой балки под действием статической нагрузки на прогиб. Программная реализация осуществлялась на языке JavaScript без сторонних библиотек. Уменьшение массы составило 25 % от массы исходной модели. Верификация оптимизированной геометрии выполнена при аналогичных условиях механического нагружения с использованием программного пакета Ansys Student. Разработанный прототип может использоваться при определении возможного процента снижения массы конструкции из композитных материалов.</p></abstract><trans-abstract xml:lang="en"><p>The object of research is composite materials, the main advantages of which include low weight of the structure and high resistance to mechanical and thermal loads. In order to predict possible loads on composite structures and take these data into account at the initial stage of parts development, computer modeling of the processes associated with them is required. A grid-less method for optimizing products made of composite materials based on elastically bonded meta-particles is proposed. The results of optimization calculations of dimensions for a test beam under the action of a static deflection load are obtained. The software implementation is carried out in JavaScript without third-party libraries. The weight reduction comprises 25% of the original model. Verification of the optimized geometry is performed under similar conditions of mechanical loading in the Ansys Student package. The developed prototype can be used to determine the possible percentage of weight reduction of a composite structure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бессеточные методы</kwd><kwd>топологическая оптимизация</kwd><kwd>структурная динамика</kwd><kwd>прочность</kwd><kwd>композиционные материалы</kwd><kwd>математическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meshless method</kwd><kwd>topology optimization</kwd><kwd>structural dynamics</kwd><kwd>strength</kwd><kwd>composite materials</kwd><kwd>mathematical modeling</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>исследования выполнены при финансовой поддержке Российского фонда фундаментальных исследований, грант 18-42-160015, и Министерства науки и высшего образования Российской Федерации в рамках исполнения обязательств по соглашению № 075-03-2020-051/6 от 06.11.2020 (номер темы fzsu-2020-0020)</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was carried out with the financial support of the Russian Foundation for Basic Research, grant 18-42-160015, and the Ministry of Science and Higher Education of the Russian Federation as part of the fulfillment of obligations under Agreement No. 075-03-2020-051/6 dated 06.11.2020 (topic number fzsu-2020-0020)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gebisa A.
