This study was aimed to verify the acceptable contact force between power collector and 3rd rail type conductor rail for the Korean standardized rubber-tired AGT light rail vehicle. The power collector was designed and manufactured to satisfy the Korean standardized Specifications of the rubber-tired AGT light rail vehicle. Based on the dynamic behavior, contact force variation and interruption in the worst installation tolerance of the conductor rail, its initial contact force was set up. At the test track for the Korean standardized rubber-tired AGT light rail vehicle, interruptions, stresses, vibrations, and contact force variations were measured. As the results, initial contact force was verified to ensure power collection stability.

In general, a third rail current collecting shoegear is widely used in the light rail transit system since it is more efficient and economical than an overhead pantograph. Therefore, its specification is prescribed in the Korean standard specifications for the light rail transit for its applications. This paper describes the development of the third rail current collecting shoegears which is suitable to Korean situation and satisfactory to the Korean standard specifications. Two types are developed for the steel wheel and the rubber tyred AGT system, and various experiments are executed. It is found that performance of the third rail current collecting shoegear developed is proved acceptable.

This study was aimed to verify the stable interruption characteristics between power collector and 3rd rail type conductor rail for the Korean-standardized rubber-tired AGT light rail vehicle. At the test track for the Korean-standardized rubber-tired AGT light rail vehicle, interruption ratios, stresses, vibrations, and contact force variations were measured by test conditions, having various train speed. As the results, it was verified that developed 3rd rail type conductor maintains interruption characteristics, which can supply stable electric power.

철도차량의 동력원은 화석연료를 사용하던 디젤차량에서 최근 고속전철 및 도시철도차량, 경량전철 등 전기를 주 동력원으로 사용되고 있다. 철도차량에 전기를 공급하는 시스템은 일반적으로 개활지 등 지상구간에 적용되고 있는 가공전차선 방식과 지하구간, 터널 등에 적용되고 있는 강체가선방식 그리고 경량전철 등에 채용되고 있는 제 3궤조방식이 있다. 최근에는 일반적으로 지하구간의 가선시스템에 적용되던 T-Bar방식의 강체가선 방식에서 탈피하여 고속주행이 가능한 R-Bar방식의 강체가선 방식에 대한 연구가 많이 이루어지고 있다. 최근까지 지하구간의 터널구조에서 강체전차선로를 급전시스템으로 채택할 경우 열차의 최고속도는 국내의 경우 90km/h, 국외의 경우 160km/h를 넘지 못하는 실정이었다. 그러나 이를 극복한 제품이 개발되어 열차운행 최고속도를 200~250km/h까지 향상시킬 수 있게 되었다. 본 논문에서는 최근 설계속도 250km/h 급 R-bar방식 강체전차선로 인터페이스를 위한 이선현상 모의 시뮬레이터 개념 설계에 관한 연구를 수행하였다. 이를 위해 집전성능과 관계가 있는 전기철도차량 이선현상 요인 및 영향 분석하였으며 강체전차선로 운행에 따른 이선 등으로 인한 영향을 고찰하기 위해 이선 현상 모의 시뮬레이터 개념 설계에 대한 연구를 수행하였다.
