Strength determination of wagon bearing structures made of round pipes at railroad ferry transportation

Abstract

The article presents the results of strength simulation of the bearing structure of freight wagon bodies made of round pipes during railway ferry transportation. In order to reduce the cost for manufacturing freight wagons, the introduction of round pipes in the supporting structure was proposed. In order to ensure the possibility of transportation of the designed structures of wagons on railway ferries, it was proposed to install on their draw bars an assembly unit for fixing with regard to decks. The value of the dynamic load which acts on the supporting structures of the bodies of the main types of freight wagons transported on the railway ferry was determined and the strength was calculated. It was established that the maximum equivalent stresses are within admissible values. The obtained results will enhance the efficiency of the operation of freight wagons through international transport corridors.
