Study of the propagation problem in the curved source of vibration

Recently, KTX start service 2004 and speed up the Chung-ang line and Ho-nam line using tilting train. When the train speed up at curve the vibration environment are changed. It is the reason of the wave propagation problem in the curved source. In this research, using SSI Program SASSI, Predict the vibration propagation around the curved source of vibration. The curved source of vibration propagation is different from straight source of vibration propagation. In this study, made a curved vibration source model and compared with straight model.
