    Transversal Displacement of Freight Wagons Bogies
    (Published by AIP Publishing, 2019) Fomin, Oleksij V.; Shvets, Angela O.; Hauser, Vladimír; Prokopenko, Pavlo
    EN: This paper is focused to the study of the influence of lateral displacement of open box type cargo wagon bogies on their main dynamic indicators and indicators of the interaction of rolling stock with rails. The theoretical study was carried out using the model of spatial oscillations of the five wagons set. During the calculations, the change in the angle of rotation of the central axis of the wagon body was considered, which leads to a mutual transverse displacement of the bogies. As a result of research, the dependences of the indicated indicators of a freight wagon on the magnitude of the angle of rotation of the body and speed of movement were obtained.
