Ride Comfort Analysis based on Heart Rate and Blood Pressure Variability according to Changed Tilting Angle at Tilting Train Simulator

The Korea is consisted of 70% mountain terrain and at existing rail road, it is many of curve railroad segment naturally. If tilting train is applied, it is unnecessary that speed of tilting train is supposed to decelerating in the curve railroad segment. As you get a hunch as term ´tilting´, the biggest feature of tilting train is the thing that is tilted when the tilting train is traveled hour. The tilting train cancels centrifugal force of the curve railroad segment at sway and is not decelerated speed of tilting train in the curve railroad segment by the tilting of train body. The TTX is acquired tilting angle range from -8deg to maximum 8deg and can get high speed at railroad which shared with low speed train. But the tilting of passenger compartment gives negative influence to passengers aspect to ride comfort. This is the important problem for long time. Moreover, it is rapidly able to decrease ride comfort by traveling of long time riding in tilting train than other train. Through tilting train simulator experiment, we are willing to know the stress, one of element of ride comfort, by monitoring change in the heart rate and blood pressure of simulator riders according to tilting angle. Considering pleasance and stability, elements of ride comfort the pleasance is restricted thoroughly and we will just only think about stability. As up-to-date engineering products, the TTX which is Korean tilting train, is necessary that passenger´s stability is guaranteed. This research is based on proving relation tilting angle and bio-signal, heart rate and blood pressure. The ride comfort research of TTX ultimately should develop by giving feedback to suspension, control part.
