Analysis on the dynamic running safety and riding comfort around curves for Korean tilting train on the Gyeongbu line

초록

In this paper, the dynamic running safety and riding comfort of tilting train was evaluated in the Gyeongbu line(between Seoul and Busan), which is considered for tilting train commercial service. The developed tilting train, 6-car prototype test train was built in December 2006. TTX is designed to run at 200 km/h, and has a planned service speed of 180 km/h. We performed the trial running test to evaluate the potential of a speed-up of tilting trains on curves in the Gyeongbu line. We also analyzed the dynamic running stability and riding comfort of tilting control though trial run train. We found a significant reduction of the journey times compared with today’s conventional trains with satisfying running performance criterion.
