Применение метода частотных передаточных функций для решения одной задачи теплоустойчивости ограждений

Abstract

Рассматривается задача о так называемом слое резких колебаний, показателе тепловой инерции и коэффициенте теплоусвоения материала. С помощью методов теории передаточных функций уточняются формулы для слоя резких колебаний. Показано, что использованный подход к решению задачи является более простым и, вследствие этого, более понятным и «прозрачным». Ранее в литературе указанные соотношения были получены путем непосредственного решения и анализа уравнения теплопроводности с соответствующими краевыми условиями. Из-за известных недостатков такого способа решения, как отмечается в литературе, отдельные исследователи предложили различные несогласованные друг с другом формулы. Использованный в данной работе метод частотных передаточных функций рекомендуется для развития теории теплоустойчивости ограждений и помещений в целом, которая актуальна и в настоящее время. The problem of the so-called layer of abrupt fluctuations, the index of thermal inertia and heat absorption coefficient of the material is considered in the article. Using the theory of transfer functions formulae for the layer of abrupt fluctuations are specified. It is shown that the approach to the problem is more simple and, therefore, more understandable and "transparent". In the previous references indicated ratios are obtained by direct analysis of the solution and the heat equation with appropriate boundary conditions. Because of the known disadvantages of this method, as noted in the references, some researchers have suggested various formulae which are inconsistent with each other. Used in this article method of frequency transfer functions is recommended for the development of the theory of thermal stability of fencing and buildings in general, which is relevant at present.
