Abstract
A mathematical model is developed for estimating the stress state of rails in the zone of rail joints. As a design scheme of the railway track, a beam is adopted in the work on discrete elastically dissipative supports with nonlinear characteristics, which makes it possible to take into account the effect of changes in the flexural rigidity of the rails on the interaction of the rolling stock and the entire structure of the upper structure of the track. The proposed model makes it possible to determine the level of the vertical dynamic forces of interaction between the rolling stock and the path in the junction zone, due to a change in the flexural rigidity of the rail thread in this zone. The obtained results can be used for a reliable assessment of the possibility of introducing new railway track structures and new types of rolling stock.
