Promising technical solutions for integrating Ukrainian and European railway transportation

Abstract

A complex of theoretical researches on solving the problems of integration of Ukrainian and European railway transport was carried out. Technical solutions have been developed to create conditions for the safe rolling stock operation on railways of Ukraine and the European Union (EU) countries, as well as for the introduction of effective freight transportation technologies. New wheel tread profiles for railway vehicles are proposed. The use of wheels with these profiles will ensure acceptable indicators of vehicles dynamic qualities and conditions of interaction between wheels and rails on Ukrainian and European railways. It will also reduce wheel and track wear. The methodology of forming disturbances acting on a railway vehicle from the track and causing its spatial vibrations has been proposed to calculate indicators of vehicle dynamic qualities. A new freight transportation technology using wagons with swap bodies has been considered for Ukraine. Recommendations on fastening elements of the swap body to the wagon undercarriage frame have been developed. The implementation of new technical solutions will increase the speed and safety of train motion, improve the interaction of the vehicle running gears with the track, and contribute to the creation of the modern Ukrainian railway complex and its integration into European transport networks.
