Abstract
The Purpose of the study is to ensure the convergence of the rail bar mathematical model and its physical model through the comparison of their amplitude-frequency characteristics in order to study a new method of tensile stress determination. The METHODS used in the study include comparison of the resonant frequencies of the results of physical and mathematical modeling. RESULTS. Having compared the results of physical and mathematical modeling, we obtained the values of resonance frequency deviations for the physical and mathematical models by the finite element method (FEM). CONCLUSIONS. The obtained convergence of the results of physical and mathematical FEM simulation of the track will allow further researches of a new method of tensile stress determination.
