Abstract

The article deals with the problem of constructing the mathematical dependence of stresses in a film from the radius of a roll in the problem of its winding in a roll. To development its dependence, we proposed using the method of a piecewise-analytical description based on the least squares method with weight selective functions. The results of research are presented in the publication confirming the possibility of developing a rather simple mathematical model by the method of selective functions what meets the requirements of modern methods of object-oriented modeling for accuracy of the approximation.
