The object of this study is the processes of emergence, perception, and redistribution of loads in the supporting structure of a 1CC size container with end walls made of sandwich panels. To reduce the longitudinal load of the container under operational modes, the introduction of sandwich panels into its design is proposed. This solution is implemented on the example of its end walls as the most loaded component of the body in operation. The thickness of the sandwich panel sheet was determined, provided that the strength in operation is ensured. Mathematical modeling of dynamic load of a container with end walls made of sandwich panels placed on a platform car during shunting co-impact was carried out. It was established that taking into account the proposed improvement makes it possible to reduce the dynamic loads that the container perceives by 10 % compared to the typical structure. The results were confirmed by computer simulation of the dynamic load of the container. The models formed within the framework of the study were verified according to the F-criterion. The results of calculations for the strength of the container showed that the stresses in its structure are 15 % lower than those in the typical one. A feature of the findings is that the proposed improvement of the container helps improve its strength in operation by reducing the loads acting on it. The scope of practical use of the results is the engineering industry, namely, railroad transport. At the same time, the conditions for the practical application of the research results are the introduction of energy-absorbing material as a component of the sandwich panel. This study will contribute to devising recommendations for designing modern structures of vehicles of a modular type and for improving the efficiency of the transport industry

The article presents the results of the strength analysis of the chain binder components for symmetry fixing a wagon on the railway ferry deck, taking into account the actual hydrometeorological conditions of the navigation area. The simulation of the wagon dynamic load during the railway ferry rolling was carried out to determine the loads acting on the chain binder. The strength of the chain binder hook was analysed. The calculation results showed that the maximum equivalent stresses in the hook occur in the radial part and exceed the allowable ones by 23%. Therefore, to ensure the strength of the chain binder, it is necessary to comply with the appropriate roll angles of the railway ferry or create measures to reduce its load when rolling. The conducted studies will contribute to ensuring the safety of wagon transportation by sea and increasing the efficiency of rail-ferry transportation.

The object of the research is the processes of occurrence, perception, and redistribution of loads in the load-bearing structure of an open wagon body, taking into account the use of an intermediate adapter. To reduce the vertical dynamic loads acting on the supporting structure of the railroad car, it is suggested to use an intermediate adapter between the frame and the load. The dynamic load of the supporting structure of the open wagon was modeled, taking into account the use of an intermediate adapter. The research was carried out in the vertical plane during the oscillations of the bouncing of the car. The results of the calculations showed that the acceleration acting in the center of mass of the supporting structure of the open wagon is 4.2 % lower than that acting on the supporting structure of the open wagon without using an adapter. The obtained acceleration results are taken into account when determining the strength of the supporting structure of the open wagon. It was established that the use of an intermediate adapter contributes to the reduction of stresses in the supporting structure of the open wagon by 6 % compared to the typical scheme of cargo transportation. A feature of the results is that the proposed solution to reduce the dynamic load of the supporting structure of the car can be implemented without improving its design. The field of practical use of the results is the engineering industry, in particular, railroad transport. The conditions for the practical use of the research results are the placement of the adapter over the entire floor area of the car body. The research will contribute to devising recommendations on reducing the load on the load-bearing structures of cars, the costs of their unplanned repairs, and to increasing the efficiency of railroad transport operation
