    In order to reduce the cost of designing and manufacturing of the new-generation open wagons, it is proposed to construct their carrying systems from round pipes. In order to exploit the proposed designs of wagons in international rail-water communication, it is assumed that they will be equipped with assemblies for fastening of chain binders. The maximal values of accelerations, as components of dynamic load acting on open wagons, made from round pipes during their transportation on a railway ferry, are determined. It is established that when moving the body in the vertical direction for a wagon located on the upper deck, the maximum acceleration value is 0.84 g, with angular displacement relative to the transverse axis for the extreme from the anchor point of the wagon body - is 0.1 g, with angular displacement around the longitudinal axis for the extreme from the bulwark of the body of the wagon - is 0.24 g. The conducted researches will enable increased efficiency of operation of open wagons through international transport corridors.

    The Substantiation Of The Concept Of Creating Containers With Viscous-Elastic Connections In Fitting.
    (2019) Fomin, O.; Lovska, A.; Daki, O.; Bohomia, V.; Tymoshchuk, O.; Prokopenko, P.
    The article presents the results of the substantiation of the concept of creating new-generation containers with viscous-elastic connections in fitting. For this purpose, a mathematical modeling of the dynamic loading of containers placed on a flat wagon while maneuvering concussion was carried out. The optimal parameters of elastic-viscous bonding in fittings are determined, in which the value of the dynamic loading of the carrier structure of the container does not exceed the normalized value. The carried out researches will promote creation of new generation containers with improved techno-economic and ecological indicators.
