Abstract
EN: 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.
