Abstract
On curved rail, the speed of train must be reduced in order to keep riding comfort. So, the train has the speed limitation in conventional railway line. But if the train has the tilting mechanism, the speed of train is able to be increased while maintaining the riding comfort. Generally, the tilting train is faster than the non-tilting train about 30% in curve. The tilting train technology and reduction of travel time has been carefully investigated by KRRI (Korea Railroad Research Institute). Based on the primary research result from KRRI, tilting control system and tilting operation interface are considered its core technology to apply tilting train to Korean conventional railway. Passenger comfort is controlled by amount of tilted car body. So the smoothness of interface between tilting bogie and car body during the tilting system operation is very important factors to estimate its capability.
