Analysis of Riding comfort effects on Tilting Control system with Hybrid curve detection

초록

Tilting trains are a kind of state of art vehicle applying active control technology in order to overcome a certain infrastructure limit of conventional commercial line. In Korea, the speed of trains could be enhanced on the existing railway network without a huge investment in infrastructure, by using tilting trains. To detect curve section in railway is very important for tilting control technology in commercial service. On-board sensor method using accelerator and gyroscope is not restricted to the track condition while having the time delay to make a bad riding comfort in transient curve area. In order to improve the riding comfort effects, we developed the hybrid method which used both on-board sensor and GPS database for detecting train position on curves. We evaluated the potential of a speed-up of tilting trains on curves, on the basis of the trial run data of tilting train on the Gyeongbu line in Korea. And we also analyzed riding comfort of tilting control though trial run train. We found a significant 30% the angular velocity improvement compared with existing method using on-board sensor.
