틸팅열차의 주행안전성과 고저틀림의 상관성 분석
Characteristics of the Running behavior and Safety for Tilting train due to Vertical Alignment
Il-Yoon Choi Ju-Hwan Um Yun-Sik Lim
ABSTRACT
Vehicle dynamic behavior should be investigated to establish the track irregularity criteria because they have an impact on vehicle dynamic behavior. The tilting train which have been developed in Korea will be operated on the conventional line. Therefore, it should be checked that the track irregularity criteria of conventional line is still available for the new vehicle. In this paper, the influence of vertical alignment on running behavior and safety for tilting train was instigated by numerical analysis. The wavelength and amplitude of vertical alignment were considered in scenario of this numerical analysis. This research is based on just numerical analysis and the final result which include measurement will be published in the future.
