Для решения поставленной задачи использована теория малых упругопластических деформаций и уравнения теплопроводности, а также апробированные численные методы. Построена целевая функция min – max от управляющих переменных, характеризующих свойства формовочного материала, из которого изготавливается оболочковая форма. Рассмотрен процесс нагрева осесимметричной оболочковой формы при заливке в нее жидкого металла. Стойкость оболочковой формы оценивается по возникающим в ней напряжениям. Составлен алгоритм решения задачи. С использованием численных схем и комплексов программ, разработанных в предыдущих исследованиях, построен алгоритм решения задачи оптимизации и найдены значения управляющих переменных. При этих значениях управляющих переменных оболочковая форма не разрушается даже при наличии жесткого процесса – заливки стали в холодную оболочковую форму. Проведен анализ влияния веса каждого из найденных параметров на значение построенной целевой функции. С помощью математического эксперимента проведено исследование морфологического строения оболочковой формы. Рассмотрена оболочковая форма из пяти слоев. Скорректированная система уравнений позволяет учитывать свойства слоев, выполненных из разных материалов. Выполнены расчеты для случая, когда слой оболочковой формы из материала, найденного оптимизацией, занимает различные положения в сечении формы; при этом остальные слои формы изготовлены из традиционной керамики. Найдено оптимальное местоположение этого слоя. Показано, что наличие нескольких слоев с найденными свойствами не влияет на повышение трещиностойкости оболочковой формы.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents a mathematical model optimizing the choice of material and morphological structure of the shell mold (SM), which has the highest resistance to cracking when pouring liquid metal into it. To solve this problem, the theory of small elastoplastic deformations and the heat equation, as well as proven numerical methods, were used. The objective function min – max was constructed from control variables characterizing the properties of the molding material of the shell. The process of heating an axisymmetric shell mold was considered when pouring liquid metal into it. The resistance of the shell form was estimated by the stresses arising in it. An algorithm for solving this problem was compiled. Using numerical schemes and program complexes developed in previous studies, an algorithm for solving the optimization problem was constructed and the values of control variables were found in which the shell mold does not break even in the presence of a rigid process – pouring steel into a cold shell mold. Analysis of the influence of weight of each of the found parameters on the value of the constructed objective function is given. Using a mathematical experiment, the morphological structure of the shell mold was studied. The shell mold of five layers is considered. The corrected system of equations makes it possible to take into account the properties of the layers made of different materials. Calculations were performed when the layer of the shell mold from material found by optimization occupies different positions in its cross section. In this case, the remaining layers of the mold are made of traditional ceramics. The optimal location of this layer was found. It is shown that the presence of several layers with the found properties does not affect the increase in crack resistance of the shell mold.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оболочковая форма</kwd><kwd>свойства материалов</kwd><kwd>напряжение</kwd><kwd>деформации</kwd><kwd>перемещение</kwd><kwd>температура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shell mold</kwd><kwd>material properties</kwd><kwd>stress</kwd><kwd>deformation</kwd><kwd>displacement</kwd><kwd>temperature</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">Литье по выплавляемым моделям / В.Н.
