Method for Running Safety Assessment of Railway Vehicles Against Structural Vibration Displacement During Earthquakes

In this paper, the authors discuss the behavior of railroad cars and vehicles that are subjected to seismic motion. A Running Safety Assessment (RSA) is conducted based on the Peak Velocity (PV) index and the Spectral Intensity (SI) index. The SI is an energy-related frequency-domain index reflecting the output intensity of the vehicle’s response. The PV index, on the other hand, is a time-domain index reflecting the intensity, or peak velocity, acting on the vehicle. The characteristics of the SI and PV assessment indices corresponding to a range of seismic motions are then compared. The results indicate that the SI index is more appropriate than the PV index in terms of accuracy and stability of assessment. A nomogram or graph for RSA corresponding to different ground classifications and denoting danger areas is also presented.
