Ride Comfort Evaluation by vertical vibration according to Tilting angle Using Heart Rate

초록

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. To tilting technique there is two types, that is, active and passive type. The TTX, Korean tilting train is active type that is separately added power and control module at connection region which is connected between the train body and the railroad. The TTX is acquired tilting angle range from -8° to maximum 8° and can get high speed at railroad which shared with low speed train. The connection region is controlled by signal of the relay system of prepared computer in train inside, GPS system and the railway line. But the tilting of passenger compartment give negative influence. Moreover, it is able to decrease ride comfort by traveling of long time riding in tilting train. In this experiment, we are supposed to know the stress, one of element of ride comfort, by monitoring change in the Heart Rate of passenger 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. The research about ride comfort of TTX which is Korean tilting train, ultimately is able to advance ride comfort of TTX by giving feedback to suspension, control part.
