2 플랜지 안내차륜 노면전철시스템의 적용성 검토에 관한 기초연구

Abstract

Interests in trams have recently increased among public transportation systems in urban areas. A tram is a transportation system that can be operated along with typical car traffic flow in a roadway. However, since the tram is operated on two rails and can be possibly mixed with traffic lanes, there is increasingly concern associated with inappropriate traffic flow. Therefore, there is a need to develop a new system to minimize these potential problems. From this perspective, this study was conducted to assess the applicability of guide wheel equipped with two flanges in trams that combines two rails by employing static and dynamic analyses. For the analyses, a guide wheel with two flanges was modeled with the properties that can be found in a commercial flange and rail system. The analyses results revealed that the applicability of the proposed system seems to be promising. The proposed system is deemed to be more suitable for roadway geometric conditions via further study on the track minimum radius curvature and corresponding tram speed in the near future.
