초록

현재 국내선로에서 운전규정에 따른 곡선반경별 속도제한을 실행하고 있으나 기존선 속도 향상과 관련하여 실제로 탈선 발생 없이 운행 가능한 곡선부 최대 통과속도에 대한 연구가 필요하다. 또한, 철도차량의 주행안전성에 영향을 미치는 요인으로서는 차량측면과 궤도측면으로 나눠질 수 있는데, 본 연구에서는 탈선 안전도 향상에 영향을 미치는 매개변수 중 레일 경좌 변화에 따른 주행안전성을 해석하고자 하였다. 탈선의 위험도가 높은 곡선부 통과하는 열차의 고속향상을 도모하기 위하여 실제 선로조건인 남성현${\leftrightarrow}$청도 상 하행 구간의 곡선부 구간별 통과시 레일 경좌와 주행속도 변화에 따른 주행안전성 해석을 수행하였다.
