“…From formula (2) it is obvious that when the train is moving downhill with the simultaneous action of the longitudinal inertia force and the wind load acting from the frontal side of the load, the load capacity of the flexible fastening elements will decrease, since in this case Qх will be like a shifting load force. As in [2,18], it is obvious that the displacement of the total center of gravity of the load of the CGоc towards the inner rail thread (-уM) with the simultaneous action of transverse inertia forces and wind load when the train is moving along a curved section of the track will contribute to an increase in the load capacity of flexible fastening elements, since in this case Qу it will be, as it were, a holding force that has a greater significance than the same force that occurs when the general center of gravity of the load of the CGоc moves towards the outer rail niche (+уM).…”

“…First, we project in a vertical plane onto the direction of projection of the flexible fastening element onto a vertical plane, and then we project directly onto the elastic element in a plane perpendicular to this vertical plane (i.e., we first lower the perpendicular to line A1М -point B, and then lower the perpendicular to line AМ -point В1) [7,9,11,14,16,18].…”

The improvement of the methodology for calculating the tension in the flexible elements of cargo fasteners with the simultaneous action of longitudinal, lateral and vertical forces on the "fastening-cargo" subsystem of the mechanical system "path - wagon – fastening - cargo" and during the movement of rolling stock, both along a straight and curved section of the track should be aimed at ensuring safety the movement of trains, safe transportation of goods on route and to ensure the safety of transport structures (vibration towers of power lines, railway bridges, etc.). There is still no mathematical model that would directly determine the tension in the flexible elements of the cargo fasteners and determine the location of the thrust bar to ensure the joint operation of the flexible and thrust elements of the fasteners.

“…Turanov and other recognized scientists to determine the height of the sorting slide, it is calculated based on the most difficult conditions -winter temperature and headwind, and for a bad runner, a four-axle empty covered wagon is selected. The reason for choosing this car was that the cross-sectional area of the closed car is larger than that of other cars (Table 1) [4,6,8,10,12,14,16,18]. The following forces act on a car moving along an inclined plane (Fig.…”

At present, in the existing methods for determining the height of a hump, the height is calculated based on the most difficult conditions - winter temperature and head wind, and a four-axle empty covered wagon is selected for a poor runner. Based on the basic law of dynamics (D’Alembert’s principle) as applied to weak links and the use of analytical formulas in the article, the calculation of the kinematic parameters of the movement of cars in the braking zone of the section of the first braking position of the hump is carried out. A sorting hump 3.08 m high is considered, for a four-axle empty covered wagon the winter temperature is -100, the headwind speed is 5 m/s m. When calculating the height of the marshalling yard, it is necessary to take the technical characteristics of a four-axle empty gondola car as a poor runner, since the headwind also acts inside the gondola car and prevents the car from rolling down the hill. It is recommended to study the effect of a headwind on a four-axle empty gondola car.
