Abstract: The object of this study is the process of loading a universal open wagon frame under operational modes. The task addressed relates to the need to improve the strength of the supporting structures of universal open wagons. To reduce the loading on the pivot beam in an open wagon frame, as one of the most loaded structural components, its improvement has been proposed. This technological advancement involves reinforcing the most loaded section of the pivot beam with a T-shaped diaphragm. The horizontal part of this diaphragm covers the most loaded zone of the pivot beam. The diaphragm is supposed to be fastened in the pivot beam by welding. The strength of the open wagon frame was calculated taking into account the proposed improvement. The finite element method, which is implemented in the SolidWorks Simulation software package, was used. The highest stress concentrations were recorded in the zones of interaction of the girdle beam with the pivot beams. It was found that the maximum stresses in the vertical sheet of the pivot beam are 4% lower than in the typical design. This proves the feasibility of the proposed improvement. A feature of the proposed technological advancement is that it does not require significant capital investments for its implementation as the cost of reinforcing diaphragms is significantly lower than the cost of repairing the open wagon frame. The scope of practical use of the results is railroad transport. The condition for using the research results is to ensure the correct technology for installing reinforcing diaphragms in the pivot beam. This study could contribute to improving the efficiency of open wagon operation by reducing the costs of its maintenance
