Abstract

The HEMU-430X is a world-class railway vehicle which aimed the maximum speed of 430km/h and the operation speed of 370km/h. To maintain high-speed operation condition over 300km/h, various requirements for satisfy exist. However, one of the most important things is a reliable supply of electricity. Especially, the dynamic interaction between the pantograph and overhead contact line at high-speed is a significant matter to pre-evaluate. In this paper, using the dynamic interaction analysis program, current collection performance of the HEMU-430X was investigated. Firstly, based on the international standard, performance of the original specifications was evaluated. In addition, through study on changes in tension and span length, improvement of the performance was considered.

차세대 고속철도(HEMU-430X)는 최고 속도 430km/h, 운영 속도 370km/h를 목표로 개발 중인 세계적 수준의 철도 차량이다. 시속 300km 이상의 운영 속도를 유지하기 위하여 충족해야 할 요건들은 다양하지만 주행 중 안정적인 전력 공급 여부는 상용화를 결정짓는 핵심기술 중 하나이다. 따라서 고속에서의 가선과 판토그래프의 동적 상호작용은 사전 평가를 통하여 충분히 검토되어야 한다. 본 논문에서는 다물체 동역학 해석 기법을 기반으로 한 집전성능 해석 프로그램을 이용하여 차세대 고속철도의 집전성능을 평가하였다. 국제 규정을 기반으로 기존 사양에 대한 성능 평가를 실시하고, 추가적으로 장력 및 경간 길이 변화에 따른 평가 결과를 토대로 집전성능 향상 방안에 대하여 고찰하였다.
