Summary:Rolling stock directly affects the economic indices of the transport industry and the national economy as a whole, leading to the need to improve control and quantify of the rolling stock dynamic load in order to maintain safe and reliable rail connections. In the process of rolling stock designing and operating, a quantitative assessment of dynamic loads is an urgent scientific and technical problem. The article presents an analysis of theoretical studies of the rolling stock dynamic characteristics on the example of open wagons, flat wagons and hopper wagons. The loading modes influence on the dynamic loading of the wagon has been studied with the aim of solving the problem of predicting the dynamics of rolling stock and indicators of its interaction with the track. The results of theoretical studies are presented taking into account the motion speed along the curved track of short and medium radius.
