초록

U 자형 전자석 하나로 부상력과 안내력을 동시에 얻는 중 저속 자기부상열차는 안내제어기 없이 곡선을 주행한다. 때문에 곡선, 특히 곡률반경이 매우 작은 곡선 주행 시에 차량이 레일과 물리적 접촉을 방지하기 위해서는 곡선형상의 결정이 세심하게 이루어져야 한다. 특히 완화곡선의 형상이 중요하다. 본 논문에서는 완화곡선 선로를 구성하는 형상 매개변수들의 차량 안내 성능에의 영향도를 분석하는데 목적이 있다. 이를 위하여 차량, 전자석, 부상제어기, 곡선가이드웨이가 통합된 3 차원 자기부상열차 다물체 동역학 모델을 개발하였고, 개발된 모델을 이용하여 곡선형상을 구성하는 매개변수 연구를 수행하였다. 연구 결과는 곡선형상의 결정이나 차량의 대차구조를 설계하는데 이용이 가능하다고 할 수 있다.

A maglev vehicle of middle-low speed subjected to both a lift force and a guidance force by a U-shaped single electromagnet is operated over a curved guideway without a guidance controller. Therefore, it is required to carefully decide the curve shape for preventing contact between the vehicle and the guiderail for the case that a Maglev vehicle is operated over a curved guideway with a small radius. Specifically, the shape of the transition curve is very important from the stability viewpoint. This study analyzes the influence of curve shape on maglev stability through parametric composition of the transition curve during vehicle guidance. To this end, a multibody dynamics-based threedimensional Maglev vehicle model was developed. The model was integrated with the vehicle, curved guideway, electromagnets, and their controllers. Using this model, a realistic parametric study including the curved guideway was carried out. The results of research should be considered usefully in the design of bogies and the curve shape.
