Theoretical and Experimental Investigations of Strength Properties of Cast Parts for Freight Cars Bogie with Axle Load of 245 kN / V. Bubnov, S. Myamlin, N. Mankevych // Transbaltica 2013 : Proceedings of the 8th International Scientific Conference. May 9-10, 2013 / Vilnius Gediminas Technical University. - 2013. - P. 9-12.http://eadnurt.diit.edu.ua:82/jspui/handle/123456789/2083S. Myamlin: ORCID 0000-0002-7383-9304EN: The cast parts of bogies for freight cars are most loaded elements, which are subject to special requirements in view of the fact that their technical condition directly affects the safety of traffic. The most stressed parts of bogies include side frames and bolster. The paper describes the results of the calculation, static and fatigue strength tests of bolster and side frame for freight car bogie model 18-1711 with axel load of 245 kN. Structural analysis was made based on allowable stress and the safety factor of fatigue strength. Analysis of the results of the calculation, static and fatigue testing results proved that design of side frame and bolster comply with all normative documents. The result of the complex theoretical and experimental investigations have provided confirmation of the selected constructive solutions bolster and side frame for bogie with a axle load 245 kN, which confirms the possibility of their use in the manufacture of freight cars.enжелезнодорожный транспортподвижной составгрузовые вагонытележкинаучные исследованиязалізничний транспортрухомий складвантажні вагонивізкинаукові дослідженняrailway transportrolling stockfreight carscartsresearch studiesКВВГThesis
