摘要：
In this paper, variation of wheel-rail forces in dynamic train-track interaction at high speed track is investigated. To analyze track and train dynamically, a model of standard fleet and train is provided. To model the loads of track and train realistically, the ADAMS/RAIL software is used. In modeling of a car by ADAMS/RAIL, an ERRI standard model of the car on a high speed track with corrugated rail (1 mm amplitude, 1 meter wavelength and total length of 5 meters) is provided. To verify the equations of dynamic load factors, offered in some codes, the software outputs and equations are compared to judge. The results of the dynamic analysis of the train shows that the equations offered in GRE manual are more applicable than those offered in others codes.
