Disclosed is a method for simulating a curved track for evaluating the stability of a magnetic levitation train. According to embodiments of the present invention, in the simulation method, a vibrational mode may be considered in dynamic characteristics analysis by assuming that a vehicle body is a flexible body rather than a rigid body in a train simulation modeling which simulates a situation of a magnetic levitation train driving on a curved track. Accordingly, since vibrational characteristics that are not extracted when the vehicle body is assumed to be a rigid body can be confirmed from dynamic characteristic data generated as a result of the simulation, so that more reliable and accurate dynamic characteristic analysis is possible when driving the curved track of the magnetic levitation train.

    자기 부상 열차의 안정성 평가를 위한 곡선궤도 시뮬레이션 방법이 개시된다. 본 발명의 구체예들에 따른 시뮬레이션 방법에서는 자기 부상 열차가 곡선궤도를 주행하는 상황을 모사한 열차 시뮬레이션 모델링에 있어서 차체를 강체(rigid body)가 아닌 유연체(flexible body)로 전제함으로써 동특성 해석에 있어 진동 모드(vibrational mode)를 고려할 수 있다. 이에 따라 시뮬레이션 결과 생성되는 동특성 데이터에서 차체를 강체로 전제하는 경우 추출되지 않는 진동 특성을 확인할 수 있으므로, 자기 부상 열차의 곡선궤도 주행시 보다 신뢰성 있고 정확한 동특성 해석이 가능하다.
