Study of the Feasibility of Using Y25 Bogies Under a Long Flat Wagon
Santrauka
Improved operational performance of international rail systems necessitates exploring the use of modern bogie designs. Therefore, there was studied the possibility of using the Y25 bogies under flat wagons, which are intended for international transportation. An important aspect of cargo transportation in international communication is the minimization of their delivery time. In this regard, the main parameters of the disc brake were calculated. At the next stage, the indicators of the flat wagon dynamics were researched. Variants of containers transport in a loaded state and in an empty state were considered. The flat wagon running for both studied options was rated as “excellent”. The strength of the flat wagon frame was calculated. It was found that the design stresses are by 15% lower than those arising in the flat wagon structure on the 18–100 bogies. The conducted research will contribute to increase the efficiency of modern and highly efficient rail vehicles design.
