한국형 틸팅열차의 개발 현황

초록

After five years of development, the prototype Korean Tilting Train was constructed. In this paper, the major systems and characteristics of the train are introduced. The tilting train has been developed to speed up and promise a significant enhancement in service quality on the conventional network of Korea. The hybrid composite bodyshell composed of honeycomb sandwich panels and stainless steel beams reduces the structural weight and secures stability on the curve. Tilting control up to 8 is initiated by gyro sensors and GPS, which provides more comfortable cornering. The self steering device in the bogie mitigates the lateral force in the curve and contributes to running safety. 16 motors of 250 kW installed on the 8 power bogies drive the electric multiple unit composed of 6 cars at the design speed of 200 ㎞/h. Since the performance tests were finished on the factory line, it undergoes the routine tests on the conventional line and commercial service is scheduled.
