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.

The next generation high-speed train(HEMU-430X) is Korea's first electric multiple unit type, high speed vehicle resulting from a national R&D project. Tests have been conducted on the Kyungbu High Speed Line running at speeds up to 354.64km/h, and analysis of the dynamic behavior of the train was carried out to evaluate its safety. In this study, a simplified method using an accelerometer(the method specified in UIC 518 OR) was chosen to analyze the safety of the train's dynamic behavior. The section chosen for analysis section was ${\pm}10{\sim}20km/h$ with respect to the maximum speed point. In addition, we analyzed the trend of this dynamic behavior with increasing speed by comparing the analyzed values with those of UIC 518 OR. The dynamic behavior results met the limit values of UIC 518 OR and the study indicates that this trend is predicted to continue at speeds above 354km/h.
