Research on the Vibration and Matching Characteristics of the Typical Wheel-Rail Profiles of High-Speed Railway in China

Hou, Maorui / Hu, Xiaoyi / Cheng, Di / Li, Lan

In order to research on the vibration and matching characteristics of typical wheel-rail profiles, a long-term experimental test on the line A and line B lasting one year was conducted to record the wheel wear. The wheel wear, worn distribution and wheelset conicity is investigated for one continuous reprofiling cycle on high-speed line A and B in the China. The simulation model of a high-speed train is established using the Simpack multi-body dynamics software package, and the simulation results agree very well with field test in time-domain. Typical results of simulation are illustrated for the vibration characteristics. The conicity of line A remains stable with the increase of operation distance, and the corresponding carbody and bogie frame vibration acceleration frequency is basically stable. The conicity of line B increases with the increase of operation distance, and the corresponding carbody and bogie frame vibration acceleration frequency is higher.
