초전도 유도 반발식 자기부상 캡슐트레인 차량의 단면적 및 길이에 따른 동특성 분석

초록

In this study, the dynamic characteristics of a superconductor electrodynamic suspension levitated capsule train were analyzed and compared according to the vehicle's cross-section area and length. Five vehicle design models for the capsule train were defined by considering the tube diameter, the number of passengers, and the number of superconductor magn ets required for vehicle levitation.A dynamic characteristic analysis model was developed for each design. The developed models includedthe levitation and guidance stiffnesses between the bogie and the tube guideway that are generated during operation, and guideway irregularity was applied as an external disturbance. Matlab Simulink wasused to realize the developed models and simulate the dynamic characteristics of each one. The vertical,lateral, roll, pitch, and yaw motions of bogies and the carbody were analyzed. As a result of the dynamiccharacteristic analysis, it was found that the increase of vehicle mass due to the increase of the cross-section area and length makes the bogie displacement increase and the carbody acceleration decrease. In the case of vehicles of the same weight, it was found that increasing the cross-sectionalarea was more advantageous for the rotational dynamic characteristics and less affected by the speedthan increasing the length.
