Abstract
The main principles of the construction and operation of the software complex for estimating the stress-strain state of structural elements of the upper structure of the track under the influence of spatial forces from the rolling stock are determined. The proposed software package is based on a step-by-step definition of the spatial forces of interaction between the dynamic system "crew way" and subsequent evaluation by the finite element method. As a computer implementation of the finite element method, the program "Lira" was adopted. Design models of rails, elements of intermediate rail fasteners, sleepers and ballast are developed. The modeling is based on the modular principle, which allows, depending on the nature of the task, to calculate the section of the railway track, practically of any length. The structural and physical non-linearity of their work, the presence of frictional forces and one-way connections between individual nodes and details were taken into account when modeling railway track elements.
