Abstract
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 0.84g, 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 0.24g. The conducted researches will enable increased efficiency of operation of open wagons through international transport corridors.
Highlights
The increased rates of cargo transportation across the territory of Ukraine, which is a link of the more important transport corridors between Europe and Asia, call for introduction of the new designs of wagons, with improved technical and operational parameters
To determine the dynamic loading of the open car body during a shunting, a mathematical model was made, the results of which were taken into account in the study of the strength of the open car body, taking into account the operational wearing of structural elements
In order to determine the dynamic load that acts on the carrying structure of the open wagon body when being transported on a railway ferry, the mathematical model, presented in [18], is used
Summary
The increased rates of cargo transportation across the territory of Ukraine, which is a link of the more important transport corridors between Europe and Asia, call for introduction of the new designs of wagons, with improved technical and operational parameters. It is known that one of the most demanded types of cars is an open wagon. In order to increase the efficiency of the open wagon operation and reduce the cost of their production, it is necessary to find new alternative solutions for their design while ensuring the conditions of durability and operational reliability [1,2,3,4]
