Abstract

The reduced-scale experiment system of rail vertical vibration is built based on the vehicle-rail vertical coupling dynamics and similarity theory and the calculation method of its key parameters are elaborated. Based on the operation of railway vehicles, a loading car along the track is designed, which can implement loading on the moving vehicle. By employing virtual instrument technology, the data collection of the test bench is achieved. By comparing the model simulated result and its experimental counterpart, it is shown that the reduced-scale vertical vibration experiment system can simulate the low frequency vibration characteristics of vehicle-rail vertical coupling vibration.
