dc.description.abstractОписано формування фізичних моделей фітингів вентиляційних систем в умовах зміни лінійних розмірів та форми суміжних ділянок повітропроводів систем вентиляції. Отримані результати призначені для застосування на заготівельно-монтажних підприємствах під час виготовлення та реалізації трубних заготовок для монтажу системи вентиляції та кондиціонування у виробничому приміщенні. Наведено побудову розгорток фітингів вентиляційних систем для різних вихідних умов, а також запропоновано графічні та аналітичні залежності. Результатами досліджень обґрунтовано отримання мінімальних відходів під час виготовлення та реалізації вентиляційної трубної заготовки різних діаметрів заготівельно-монтажним підприємством. Мета роботи – досягти мінімізації відходів матеріалів під час виготовлення та реалізації трубної заготовки різних діаметрів вентиляційної системи, зменшення металоємності, підвищення продуктивності виробництва та ефективності заготівельних робіт для монтажу системи вентиляції у виробничих приміщеннях, виявити способи підвищення ефективності монтажу системи вентиляції у виробничих приміщеннях різного призначення та обґрунтувати методики розрахунку. Отримані результати дають змогу мінімізувати відходи, за рахунок цього зменшити металоємність матеріалів та підвищити продуктивність виробництва та ефективність заготівельно-монтажних робіт. Застосування отриманих фізичних моделей для визначення необхідних параметрів під час виготовлення розгорток фітингів вентиляційних систем дає змогу значно підвищити критерії ефективності виконати заготівельно-монтажних робіт і тим самим зменшити витрату матеріалів для виготовлення і монтажу вентиляційної системи.
dc.description.abstractThe article presents the formation of physical models of fittings of ventilation systems in the conditions of change of linear sizes and forms of adjacent sections of air ducts of ventilation systems. The aim is to minimize waste materials in the manufacture and sale of pipe billets of different diameters of the ventilation system, reduce metal consumption, increase production productivity and efficiency of procurement for installation of ventilation in industrial premises, identify ways to improve the installation of ventilation in industrial premises for various purposes and justification calculation methods. The use of the obtained physical models to determine the required parameters in the manufacture of sweeps of ventilation system fittings can significantly increase the efficiency criteria for procurement and installation work.
