Abstract

This study aims to investigate the dynamic interaction characteristics between Maglev vehicles and an elevated guideway. A more detailed model for the dynamic interaction of the vehicle/guideway is proposed. The proposed model incorporates a 3D full vehicle model based on prototyping, flexible guideway by a modal superposition method, and levitation electromagnets including the feedback controller into an integrated model. The proposed model was applied to an urban transit Maglev developed for a commercial application to analyze the dynamic response of the vehicle and guideway, and the effect of the surface roughness of the rail, mid-span guideway deflections, and air gap variations are then investigated from the numerical simulation.

고가가이드웨이를 주행하는 상전도흡인식 자기부상열차(EMS-Type Maglev)는 가이드웨이의 유연성으로 인하여 전자석 현가시스템과 동적 상호작용을 일으켜 부상공극에 영향을 미친다. 특히, 전체 건설비를 줄이기 위하여 경량화 가이드웨이를 지향하면서 시스템 설계단계부터 차량과 가이드웨이 사이의 동적상호작용 해석에 의한 심도 있는 부상공극 분석이 더욱 필요하다. 본 논문에서는 보다 정교한 차량/가이드웨이 동적상호작용 해석모델이 제안된다. 제안된 모델은 가상시제 기반의 3 차원 전체차량, 모달합성법에 의한 유연 가이드웨이 및 피드백 제어기가 포함된 부상전자석의 동적 모델들이 하나로 통합된 것이다. 제안된 모델을 도시형 자기부상열차에 적용하여 차량의 속도와 레일조도가 부상공극 및 가이드웨이에 미치는 영향을 분석하였다.
