Abstract

The paper presents the research results aimed to simulate the condition of a section structure with variable stiffness in order to calculate the stress-strain condition of bodies with anisotropic properties and their calculation-based definition. The inverse task of forced frequency vibrations of a transversely inhomogeneous elastic layer with the constant thickness is considered, the results of solving which should suit the confidence interval of acceptable values. To do this, it is proposed to vary the values of the mechanical anisotropic characteristics of the structure. On the basis of the mathematical solution of the engineering problem connected with the deformation of the permanent way under the moving dynamic loading, vertical deflection curves are drawn for various parameters of a reinforcing structure.
