Application of Normal Pantograph to Tilting Vehicle with Technical Modification of Vehicle System

일반 판토그라프의 틸팅차량 적용을 위한 차량시스템의 개선안

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 interlace are considered its core technology to apply tilting train to Korean conventional railway. In this paper application of non-tilting pantograph to tilting system will be introduced. New type of bogie frame and system modification of vehicle are invented to apply non-tilting pantograph to tilting train.
