APPLICATION OF FREQUENCY RESPONSE FUNCTION METHOD TO SOLVE A PROBLEM ON THERMAL STABILITY OF FENCING

Abstract

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.
Keywords: layer of abrupt fluctuations, amplitude, the rate of thermal inertia, the coefficient of
heat absorption of the material, the frequency response function.
