The Influence of Seismic Motion with Ground Irregularity on the Dynamic Behavior of Railway Vehicles

In order to check the safety of trains running on railway structures, it is essential to take into account the characteristics of earthquake motion. In soft ground with a non-flat base, waves are generated over a slanted base area and propagate in the horizontal direction. The behavior of railway vehicles is therefore affected by these horizontally propagating waves. In this paper, we clarify the effects of wave propagation characteristics on the dynamic behavior of railway vehicles by numerical simulation.
