The scope of the study: the operational patterns of wagon constructs and the laws of their development with subsequent presentation by means of flash concepts, scientifically-grounded with dynamic and strength modelling. The study includes the following research methods: the dynamic loads on the wagon constructs under operating loads are determined with classical methods of oscillation theory, wagon dynamics and theory of ship motion; the optimal parameters of the bearing structures of the rolling stock are determined with the optimization theory; the strength of the wagon constructs is studied with the methods of material resistance and construction mechanics, as well as the finite element method; and the adequacy of the developed models is verified with the Fisher method. The theoretical results obtained are experimentally verified using the method of strain measurement on real objects of research. According to the results, the study proposes the method for taking into account the excessive loads on the bearing structures of wagons and containers in operation (train-ferry transportation, shunting impacts of flat wagons loaded with (tank) containers with elastic, viscous and viscoelastic connections in fittings); presents the mathematical models that allow obtaining refined dynamic loads on wagons in the most unfavourable operating modes, as well as the dependence of their dynamic load under these modes; and proposes the concepts of the bearing structures of wagons and containers including the obtained dynamic loads that will contribute to better efficiency of railway operation Product Description popup.authors Ivanchenko Dmytro Anatoliiovych Hordiienko Denys Anatoliiovych Hrybanov Mykola Vitaliiovych Klieshchov Oleksandr Rostyslavovych Lovska Alyona O.
