“…Правильная установка колесной пары в рельсовой колее позволяет обеспечить оптимальный контакт между колесом и рельсом в зоне, близкой к оси симметрии рельса, что значительно уменьшает уровень контактных напряжений и в итоге влияет на общий ресурс надежной работы как рельсов, так и всей конструкции железнодорожного пути в целом [6,7].…”

Purpose: Calculation of an economic effect by introducing the parameter of equivalent taper of wheel pairs on account of reduction of operating costs on high-speed train motion and track facility maintenance. Methods: The study used the methods of computer simulation of interaction between a rolling stock and a railway track, methods of mathematical statistics, methodology to make traction calculations in automated system. Results: Measures have been proposed to reduce the forces of a drag for a high-speed rolling stock motion. We’ve calculated an economic effect from introduction of wheel pair equivalent taper parameter on Russian Federation high-speed railroads. Practical importance: Recommendations have been proposed on consideration of wheel pair equivalent taper parameter for to reduce the forces of drag to the motion and on pursuing rail mobile treatment on the sections of high-speed train traffic sections.
