Abstract

As standard of living is higher and aging society is coming, it is needed to develop transportation that is easy to use for weak person. To comply with the demands, it is started to make Bi-modal Tram that is on KRRI(Korea Railroad Research Institute)'s hands. This tram has to have good accessibility like bus, be low level from ground like subway, and park accurately so wheel chair's or passenger's foot can't fall into the gap. But Bi-modal Tram have long length, so it need development of All Wheel Steering System. The Bi-modal Tram that have all wheel steering system steer not only the first axle but also the second and third axle from the first axle or articulation angle, and velocity, and so on. At this study, we discuss AWS ECU's development process.

삶의 질이 높아지고 고령화 사회가 시작되면서, 사회적 약자들이 사용하기 쉬운 교통수단의 개발의 필요성이 증대되고 있다. 이러한 요구에 부응하기 위해, 한국철도기술연구원에서 주관하여 저상굴절버스(Bi-modal Tram)의 개발을 시작하게 되었다. 이 저상굴절버스는 버스와 같은 높은 접근성의 특징을 가져야 할 뿐만 아니라, 지하철과 같이 차체가 낮아야 하며, 휠체어나 승객의 발이 승강장과 차량 사이 틈에 끼지 않도록 정확한 주차가 이루어져야 한다. 하지만 저상굴절차량의 길이가 길어, 이러한 요건을 맞추기 위해서는 전 차륜 조향 시스템이 개발-장착되어야 한다. 전 차륜 조향 시스템이 장착된 저상굴절차량은 1축 차륜이 조향될 뿐 아니라, 1축 조향각 또는 굴절각과 속도 등의 상태에 따라 2축과 3축 차륜이 조향되는 특징을 가지고 있다. 본 연구에서는 전 차륜 조향장치의 개발 과정을 다룬다.
