Rail/Wheel Dynamics Simulation for the Transition Curve of the High Speed Test Section of the Qinshen Passenger Railway Line

Using the large wheel/rail dynamics simulation software package NUCARS developed by the Association of American Railroads (AAR), the authors have analyzed the wheel/rail dynamics behavior when high speed cars run in high-speed sections of the Qinshen Passenger Railway Line with a cubic parabola transition curve and have compared with the half-wave-length sinusoidal transition curve present with the Japanese Shinkansen Line. Also, the authors have made comparing wheel/rail dynamics simulation for different cant setting methods of the Chinese type and the Japanese Shinkansen type. The research results show that the existing type of the transition curve and the Chinese type of cant setting are able to ensure safety and comfort in the high speed tests in test sections of the Qinshen Passenger Railway Line.
