Study of Ride Comfort on the Korean Tilting TraineXpress through Bio-signal indices

초록

Seventy percent of Korea’s terrain is mountainous. Many of the curves on existing railroad lines are naturally segmented. A tilting train requires a minimal amount of deceleration when navigating curves. This is because the vehicle cancels the centrifugal force of a curved railroad segment by leaning into the curve, eliminating the need to slow down. The most important feature for passenger comfort in a tilting train is the degree of tilt. The tilting angle of a Korean tilting train, the TTX, varies from -8° to a maximum of 8°, enabling the train to maintain high speeds on a railroad line that is shared with low-speed trains. However, the tilting of the passenger compartment has a negative influence on passenger comfort, especially for riders who are traveling long distances.
