Abstract
The article presents result of computational modelling of container dynamic load during transportation as a part of trains of intermodal transport on a railway ferry. The computational models were developed which account the movement of the container with regard to the frame of the flat wagon while moving of the railway ferry. It was assumed that there is no movement of the flat wagon with regard to the deck, since these movements were limited by fastening means. The obtained acceleration rates, as components of the dynamic loads acting on the container, were accounted while determining the containers stability coefficient with regard to the flat wagons. The railway ferry heeling angles which ensure the stability of the containers were determined. The researches will ensure safety of transportation of containers as a part of trains of intermodal transport on a railway ferry, as well as increase the efficiency of operation of intermodal transport in the international transport.

The development of international economic activity between Eurasian countries enables the commissioning of competitive transport systems
The trochoidal law of the moving action on the railroad ferry with wagons located on its decks and the dissipative component that occurs during the fluctuations of the railroad ferry in the conditions of the sea disturbance were taken in account during developing the model, as well as the wave-to-course angle in relation to the railroad ferry hull and the wind load acting on the uncovered projection of the railroad ferry, the flat wagon located on the upper deck and containers
The computational model for determining the dynamic load of a container placed on a flat wagon during transportation by a railroad ferry was developed
Summary
The development of international economic activity between Eurasian countries enables the commissioning of competitive transport systems. Container transportation as a part of intermodal trains was expanded to reduce the time of cargo delivery and transportation costs. These trains can run in relation to main-line railways, and in international rail and water transportations involving railroad ferries. It is important to study the load of intermodal trains to ensure the safety of their transportation on railroad ferries, as conditions for the container transportation by sea are significantly different from the conditions of their operation relative to the main-line railways. The article focuses on the issue of researching the dynamic load of containers during transportation as a part of intermodal trains on railroad ferries and determining the permissible heeling angles at which the stability of containers is ensured in relation to flat wagons
