Modeling of the transition section of a railway track with and without ballast structures

Abstract. The current development of the country's transport systems and individual settlements is associated with the construction of new and reconstruction of existing railway tracks. The articulation of various types of railway track structures is a "weak point" both from the point of view of calculating the elements of the upper structure of the track according to the limiting conditions of the first and second groups, and from the point of view of the source of noise and vibration due to the stiffness difference of the base. The article is devoted to the development of a mathematical model of a railway track during the transition from a ballast track structure to a ballast-free one, in order to ensure the smooth movement of rolling stock, and also make it possible to predict the choice of material and type of base structure. The solution being developed is aimed at creating a double algorithm, which can be used to calculate different cases of articulation of different path structures. The proposed solutions can be generalized to a railway track laid through artificial structures.
