Study and Application of High-Speed Railway Real-Time Dynamic Response Based on Running Simulation

Abstract:

In order that the vehicle-track dynamic simulation can reflect the actual operation better, the running simulation theory was introduced into the analysis process of the high-speed railway dynamic response. Firstly, the data (including time, mileage, velocity, acceleration, etc.) of train running simulation was worked out by traction calculation. Secondly, according to the structure feature of high-speed railways vehicle and track, the vehicle-track coupled dynamic model was built. Non-linear Hertz theory was used for modeling the wheel-rail contact. Then the wheel-track creep force was obtained by using Kalker's creep theory and Shen's non-linear theory. Meanwhile, various track spectrums were simulated. Furthermore, the running simulation data as the original data were used to work out the real-time dynamic response indices in the dynamic calculation process. Thirdly, the indices would be applied to the alignment comfort evaluation. Finally, the system was developed out and the rationality and practicability of the method were verified through an example.
