Математичне моделювання динаміки контейнера-цистерни, розміщеного на вагоні-платформі при маневровому співударянні

Abstract

UA: У статті наведено дослідження динаміки несучої конструкції контейнера-цистерни, розміщеного на вагоні-платформі, при маневровому співударянні з урахуванням зазорів між фітингами та фітинговими упорами, а також переміщення наливного вантажу відносно котла. Результати досліджень дозволили отримати уточнені величини прискорень, які діють на несучу конструкцію контейнера-цистерни при маневровому співударянні.

EN: The combined transport systems have been developed to improve the efficiency of the transportation process in the direction of international transport corridors. The intensification of liquid cargoes transportation via the territory of Ukraine determined the creation and introduction of tank-containers. To ensure the strength of tank-containers in operation there are a number of regulatory documents regulating requirements for their design and operating conditions. The mathematical model was createdto determine the quantities of operational loads which act on a tank-container placed on a train platform when a train shunting collision, considered as the greatest event of loading of the support structure. When a model was created it was taken into account the gaps between the fittings, tank containers and fitting supports the train platform and liquid cargos movement towards the boiler. The research results allowed to obtain more accurate values of specified accelerations that act on the supporting structure of a tank-container during shunting collision. The maximum accelerations were recorded for the case, when the gap between the fitting and the fitting supports was 30 mm. The research can improve the safety of tank containers when shunting collision and can be used in designing of tank-containers of new generation with increased technical, economic and operational performance.
