Investigation into the dynamic load of the container with sandwich panel walls when transported by train ferry

The article presents the results of the study into the dynamic load of the container during its transportation by the train ferry. The peculiarity of the container is that its walls are made of sandwich panels. Such a solution will help to reduce the dynamic loads acting on the container at operating load modes, including when transported by sea as part of combined trains. To determine the dynamic loads acting on the container, a mathematical model was build that took into account the angular displacements around the longitudinal axis of the system “train ferry – flat wagon – container – freight”. The calculations were made for the train ferry Geroi Plevny. The mathematical model was solved in MathCad. It was found that the value of acceleration acting on the container of the proposed design during transportation by sea was 4.3% lower than that acting on the container of a typical design. The acceleration value obtained, as a component of the dynamic load, was taken into account to determine the stability coefficient of the container in a typical diagram of its interaction with the flat wagon. The roll angle of the train ferry, at which the stability of the container placed on the flat wagon is ensured, was also calculated. The results of the study will contribute to the database of recommendations for the design of modern container structures and their safe operation in international rail and water traffic.
