Study on the Running Safety of Railway Vehicles in Earthquake : Analysis with Multibody Dynamic System and the Model Vehicle Experiment

Abstract

Some experimental investigations were carried out to get the relation between the safety limit of excitation displacement value and excitation frequency. In this experiment, the video images by two high-speed cameras were obtained and the strong reproducibility of an derailment phenomenon was checked. The simulations were performed using the mechanism analysis program DADS (Dynamic Analysis and Design System). The converted result of model experiment and a simulation result showed the tendency similar to the simulation result of Railway Technical Research Institute.
