고저틀림에 따른 차세대고속열차의 주행안전성 영향 분석
Characteristics of the Running behavior and Safety for HEMU-400X due to Vertical Alignment
Il-Yoon Choi Chan-Kyoung Park Ju-Hwan Um Yun-Sik Lim
ABSTRACT
HEMU-400X train have been developed and will be operated over 350km/h. In this paper, the influence of vertical alignment on running behavior and safety for HEMU-400X 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.
