Molchanov V. The determination of elastodynamic track characteristics and their impact on the force interaction on the frogs

The goal - a study elastic dynamical parameters of the way to the track switches and set the level of the power load switches when passing the wheels rolling on the vertical irregularities on the grooved spiders. Object - the processes of force interaction track and rolling stock on the track switches. Methods - empirical and theoretical studies, the experimental measurements, the theory analysis of beams on elastic foundation and the method of initial parameters, methods of mathematical modeling and computer numerical calculations. Novelty - improved method for determining the elastic dynamical parameters of the way and turnouts for the first time in the country's science brought to the level of practical engineering calculations, theoretical solution to this problem. An experimental study of geometrical irregularities on the crossings turnouts on reinforced concrete bars, characteristic and the average roughness. A new mathematical model and the method of calculating the dynamic interaction forces of the "path-rolling" on crossings turnouts. A new method of calculation of internal forces in the bars of switches for the effects of non-loaded rail threads. The theoretical and practical results allow to estimate the power load, and therefore the strength and reliability of switches, as well as set the allowable speed for the operating conditions. Scope - Company railroad lines and related research, design and educational institutions.
