| Abstract: | Field test and theoretical analysis of wheel-rail dynamic interaction are conducted under normal conditions, rail corrugation state and polygonal wheel at different speeds of EMU to study the wheel/rail interaction law under the conditions of 380 km/h, 400 km/h or even higher speed. The result can be used as guidance for optimization of wheel and rail materials and structure and is of great significance for improvement on high speed railway engineering design and construction expertise in China. |
