In this article, the definition of the current density field at current collection was reduced only to the calculation of the thermal (resistive) action of the electric current. These procedures must include consideration of the bending stiffness of the contact wires to calculate the distribution of the pressing force on the contact wire between the current collecting plates. Therefore, it is necessary to improve the existing methods for calculating the dynamics of mechanical interaction of the current collector with the chain suspension. As a result of computer modeling in the Comsol Multiphysics software package, the volumetric power density of resistive heating from the intrinsic resistance of the contact wire was determined.

“…The article discusses the model and develops the procedure for calculating the reaction of the connections of the spring-friction set of the freight car trolley, which takes into account the possible edge contact of friction bodies with separate faces (Figure 1). Therefore, when creating the calculation model of the friction wedge as the subject of the study, it would be necessary to replace the surface of its contact on the side of the pressure beam and the friction level as external connections with only two coupling reactions in the form of replacing the pressure beam and replacing the friction level [6,7]. ).…”

The purpose of this article is the mathematical modeling of a spring-friction set of a freight car trolley depending on the profile of the railway track. The article uses the methodology of the results of the generalized model of power interaction of friction pairs "pressure beam-friction wedge" and "friction wedge-friction bar" of the spring-friction set of the cart 18-578 in the mechanical system "track-car-load," in a particular case cart from which such models of the e of the freight car 18-100 can be obtained. The manuscript contains a software study using a computer simulation of a freight wagon trolley, which complements the experimental studies. The mathematical (symbolic) method in the computer algebra system MathCAD (a type of computer-aided design system) is used to solve the equations of equilibrium of the supercharger beam as a real object. In the course of the experimental study, a computational mathematical model of the force action of friction pairs of spring-absorbing trolley apparatuses was developed, and the results of calculations of the reaction of the friction bar to the friction wedge were mathematically obtained. The optimal parameters were obtained analytically, and the indicators of the angles of inclination of the contact surfaces of the trolley of the freight car were justified.

“…Determination of permissible speeds and dynamic parameters of interaction between a TE33A series diesel locomotive and a railway track, when passing on a curved section with the smallest radius, is an urgent research issue. unusual for its purpose, which led to a complication of the design of the bogies, an increase in their weight and, as a result, to a deterioration in the conditions for the locomotive to pass curved sections of the track [2][3]. All these ultimately led to an increase in the horizontal forces of interaction between wheels and rails, and to an increase in the wear of wheelset bands and rails.…”

The purpose of the research was an experimental study of the dynamic processes of interaction between a TE33A diesel locomotive and a railway track when passing along a curved section with a radius of 290 m. To study the dynamic and driving properties of the rolling stock, the analysis of the experimental data obtained was carried out. When performing the study, the following results were obtained: the indicators of the frame forces of each wheel were determined when moving the TE33A locomotive along a curve with a radius of 290 m; the coefficients of the vertical dynamics of the second suspension stage when moving the TE33A locomotive along a curve with a radius of 290 m are determined; axial stresses in the rails under the influence of the TE33A locomotive on the track with rails of grades R50 and R65 are determined.
