Abstract

Тема выпускной квалификационной работы: «Моделирование теплопередачи в формовочных смесях». Работа посвящена проведению численного анализа процесса теплообмена и определению эффективных теплофизических свойств формовочных смесей на основе кварцевого песка и жидкого стекла. Проведено изучение теплофизических характеристик формовочной смеси на основе варьирования основных параметров исследования - количества связующего и диаметра зерен наполнителя. Разработан алгоритм для реализации перспективного развития программного обеспечения путем моделирования условий формирования насыпной плотности и степени деформации пленки связующего при уплотнении смеси. Методом математического моделирования с помощью программного пакета “SVIAZAN” проведен анализ совместного влияния структурных характеристик формовочных смесей, необходимых для определения их теплофизических параметров. Исследованы температурные зависимости локально-эффективной теплопроводности формовочных смесей при изменении среднего диаметра зерен наполнителя и количества вводимого жидко-стекольного связующего. Разработана математическая модель, ориентированная на развитие информационного обеспечения и расчетного аппарата для компьютерного моделирования теплофизических характеристик формовочных смесей.

The subject of the graduate qualification work is “Modeling heat transfer in molding sands”. The given work is devoted to numerical analysis of a heat transfer and defining the properties of molding sands based on silica sand and liquid glass. Studying thermophysical properties of a molding sand. The studying made in the qualification work is based on parameters manipulation, such as: 1) binder quantity, 2) grain diameter. The algorithm for growth prospect of the software was developed. The analysis was conducted by the method of mathematical modeling with the use of the “SVIAZAN” software package. The study resulted into data analysis of linking the structural factors of the molding sand. The temperature dependency of the mold sand thermal conductivity has been studied. The research has shown the complicated relation between local thermal conductivity of the sand and the grain diameter with the quantity of the binder. An algorithm aimed at developing the modeling software has been developed.
