Нередко их производство сопровождается дефектами, ухудшающими макроструктуру изделия. В связи с этим актуальны новые методики, позволяющие моделировать процессы формообразования поковок с ребрами жесткости. Процессы обработки металлов давлением сложны в создании математической модели, описывающей напряженно-деформированное состояние пластического формообразования металла. Одним из способов решения задачи моделирования картины течения металла и пространственной эпюры контактных давлений является «теория течения тонкого слоя», основанная на допущениях, упрощающих исходную систему дифференциальных уравнений. В этом случае задача сводится к чисто геометрической и может быть решена в рамках «песчаной аналогии» с помощью предложенной методики. Приведены результаты компьютерного и физического моделирования формообразования штампованной поковки с контурным оребрением. Эксперимент проведен в промышленных условиях по осадке плоских заготовок из сплава АК6 на гидравлическом прессе силой деформирования 150 MН. Показано, что предложенный программный комплекс может иметь различное функциональное назначение: экспресс-анализ картины течения металла и расчет формоизменения заготовки на стадиях ее деформирования. Это позволяет, перебирая значения геометрических параметров гравюры штампа, получать разные картины течения металла и профили ребер жесткости и выбирать из них те, которые гарантируют наиболее равномерное заполнение металлом полостей штампа под ребра жесткости, что обеспечивает бездефектное получение изделия.</p></abstract><trans-abstract xml:lang="en"><p>Parts made of the billets with a thin web and stiffeners are manufactured at metallurgical enterprises in special workshops equipped with powerful hydraulic presses. Often their production is accompanied by the defects that worsen the product macrostructure. In this regard, new techniques are relevant that allow modeling the processes of forming of forgings with stiffeners. The processes of metal treatment by pressure are difficult to create a mathematical model describing the stress-strain state of plastic forming of metal. One of the ways to solve the problem of modeling the pattern of metal flow and the spatial diagram of contact pressures is the “theory of thin layer flow”, based on assumptions that simplify the initial system of differential equations. Then the problem is reduced to a purely geometric one and can be solved within the framework of the “sandy analogy” using the proposed methodology. The paper presents the results of computer and physical modeling of the forming of stamped forgings with contour stiffeners. The experiment was carried out in industrial conditions on the precipitation of flat billets made of AK6 alloy on a hydraulic press with a deformation force of 150 MN. It is shown that the proposed software package can have a different functional purpose: express analysis of the pattern of metal flow and calculation of the shape of the billet at the stages of its deformation. This allows, by sorting through values of the geometric parameters of the stamp engraving, to obtain different patterns of metal flow and profiles of stiffeners and choose from them those that guarantee the most uniform filling of the stamp cavities with metal under the stiffeners, which ensures defect-free production of the product.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>штамповка</kwd><kwd>течение металла</kwd><kwd>математическое моделирование</kwd><kwd>физическое моделирование</kwd><kwd>программное обеспечение</kwd><kwd>формообразование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stamping</kwd><kwd>metal flow</kwd><kwd>mathematical modeling</kwd><kwd>physical modeling</kwd><kwd>software</kwd><kwd>forming</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">Сосенушкин Е.Н., Кадымов В.А., Яновская Е.А.
