초록

차세대고속열차는 국가 연구개발사업으로 국내에서 최초로 개발한 동력분산식 차량이다. 차세대고속열차의 성능시험을 위해 경부고속 구간에서 속도 354.64km/h 까지 1차 시운전을 종료하였다. 따라서 주행안전성을 위해 대차 및 차체의 동적 거동 분석을 통한 안전성 평가가 필요하다. 본 연구의 동적 거동 안전성 분석방법은 UIC 518 OR의 가속도계를 이용한 단순방법(Simplified method)를 이용하였고, 분석구간은 최고속도 지점 기준으로 ${\pm}10{\sim}20km/h$ 범위로 하였다. 이에 분석된 결과 값을 UIC 518 OR의 제한기준 값과 비교하여 차량마다 해당속도에서의 동적 거동과 속도증가에 따른 경향을 분석하였다. 본 연구의 결과, 동적 거동 분석결과는 UIC 518 OR 제한기준에 모두 만족하였고, 이러한 경향은 속도 354km/h이상에서도 지속될 것이라 예측된다.
