Study on High-Speed Train Terminal Speed Based on Adhesion Utilization

Abstract:

The terminal speed of wheel/rail train is being concerned in the era of high-speed train. The number of terminal speed represents development level of wheel/rail train. In this study, the calculation formulas of basic resistance and calculation adhesion of the "Harmony" EMU were used. It was assumed that the traction power is enough large, and the terminal speed of high-speed train was obtained by calculating for dry rail surface and humid rail surface. The average terminal speed was calculated by the area-method. Randomly variational adhesion coefficient was simulated, and the necessary and sufficient conditions for the terminal speed were derived.
