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.
