To minimize the risk of fatalities in the event of earthquakes, it is extremely important to prevent the derailed vehicle from deviating from the track as well as to prevent the vehicle from derailment. Authors have developed a post derailment stopper (hereinafter referred to as, “stopper”), which attaches to a bogie frame and prevents derailed vehicles from veering of the track. For the development of the stopper and evaluation of its efficacy, we conducted running tests under derailment conditions using real bogies and tracks. Based on the results of the running tests, we have developed a 15DOF vehicle dynamics model in order to discuss the motion of the bogie in the derailment condition. In this model, focusing on the analysis of the motion of the bogie and the stopper, vertical wheel displacements which were measured at the running tests are used as input data and non-linear characteristics observed at the running tests are considered. In this paper, we analyze the motion of the bogie and efficacy of the stopper with this model and the test results.
