The study deals with a shunting impact of 13-4085 wagon platform to a TK25 tank container. In order to define the loads acting on the container frame, 3D computer models of the 1СС size container is designed, both version – for liquid and dry material transport. The virtual model consider a longitudinal force from the wagon automatic coupling, vertical and horizontal forces from the wagon – containers interaction and also vertical forces of the container fittings. For checking adequacy of the created models, the container acceleration values was obtained in two scenarios. In the first case, when fittings are aligned relative to the fitting spots of a wagon, thus without possibility of relative movement. In the second case, movement within clearance of fitting spots is possible. Mathematical models of dynamic loads on these structures were solved by MathCad. Differential equations were solved by the Runge – Kutta method. Adequacy of the created models was checked with an F-test. On the basis of conducted calculation can be conclude that the hypothesis on the adequacy of the models was not rejected.

This paper deals with the methods and techniques of the locomotive dynamic characteristics improvement, decrease in force impact on the track, minimizing tire and rail wear by secondary suspension improvement. Based on the calculations carried out using the created mathematical models and experimental research, there are proposed series of
construction solutions of the supporting and returning devices with rational characteristics, which allow improving traction characteristics of the locomotive and reducing its dynamic impact on the track in vertical as well as in horizontal planes, on the straight track as well as on the curved track. Moreover, the proposed solution can provide the
locomotive body with the centering function relative to the bogie. The proposed body to bogie connection was tested using a special test stand and in operating conditions. According to the test results, the proposed construction of body to bogie connection can ensure the required rigidity and damping characteristics due to the design optimization.
