Abstract
The seismic behavior of railway vehicle was investigated to consider the mechanism of derailment by an earthquake. A scale of 1 to 10 railway vehicle model was vibrated by five types of seismic wave, which are Off Tokachi Earthquake, Niigata Prefecture Chuetsu Earthquake, Noto Peninsula Earthquake, Niigata Prefecture Off Chuetsu Earthquake and Iwate Miyagi Inland Earthquake. The speed of the vibrated model were 0km/h, 3km/h, 6km/h and 9km/h. For each condition, the model was vibrated ten times and derailment probabilities were found. By this study, it was shown that derailment probabilities tend to be higher when railway vehicle is running. Also, it was found that limits of effective value of input and response acceleration are different for stopping vehicle and running vehicle.
