The effectiveness of this solution was studied through the transverse loading of the open wagon body in operation. This included the building of a mathematical model that described the movement of a loaded open wagon during lateral oscillations. It has been found that the acceleration acting on the open wagon body is 4.1% lower than that acting on the typical design. The thickness of metal sheets forming a sandwich panel was determined by the Bubnov-Galerkin method. The strength of the open wagon body with sandwich-panel walls was calculated using the finite element method. The results of the calculation have made it possible to conclude that the stresses in the open wagon body are within the permissible limits and are lower than those acting in a typical design by 3.5%. The results of the research will contribute to the scientific development database of innovative wagon designs with improved technical and economic characteristics, and increase the efficiency of railway transport. © 2024 The Authors.
