Abstract

In a magnetic train set composed of more than two cars, the installation of dampers between cars is carefully considered for improving both the ride quality and the safety, particularly during curve negotiation. In this study, a dynamic simulation of the ride quality and curve negotiation of a Maglev vehicle was carried out. The dynamic model is developed based on multibody dynamics. The presented full vehicle multibody dynamic model integrates the electromagnet model and its control algorithm. By using this model, the effects of the dampers are numerically analyzed. The proposed damper is installed on the vehicle and tested to analyze its effects. In this study, the simulation and measured results of the vehicle behavior and ride quality are discussed.

반경이 작은 곡선이 종종 존재하는 도시 내에서 운행되는 도시형자기부상열차는 전자석과 레일 사이에 기계적 접촉 없이 곡선주행을 할 수 있어야 한다. 특히, 안내제어가 없는 자기부상열차에 있어서는 승차감을 확보하면서 곡선추종성능을 향상시키기 위하여 차간 댐퍼의 설치가 고려된다. 자기부상 차량용 차간 댐퍼는 곡선 진출입시 차량에 발생하는 요(Yaw) 방향의 진동을 최소화할 수 있어야 함과 동시에, 부상 전자석이 레일과 접촉이 없도록 해야 한다. 본 논문에서는 곡선주행에서의 차간 댐퍼의 승차감과 곡선추종성에의 영향을 분석하는데 목적이 있다. 이를 위하여 부상제어, 차량, 대차 및 궤도가 포함된 동역학 모델을 이용한 동특성 시뮬레이션이 수행된다. 시뮬레이션을 통하여 차간 댐퍼의 효과가 분석되고 시험 선로에서의 주행시험을 실시하여 해석 결과의 신뢰성에 대한 검증이 이루어졌다.
