본 논문은 철도에 사용되는 전차선로-집전계 주행시험기용 고속 리니어 추진시스템의 설계를 제안한다. 여러 가지 다양한 추진시스템 중에서 요구사양을 만족하며 짧은 구간에 높은 가속력을 제공할 수 있는 영구자석형 선형동기전동기를 선택하였다. 설계는 전동기의 특성식과 등가자기회로법을 이용하여 수행하였으며, 유한요소법을 이용하여 이를 검증하였다. 또한 실험계획법을 통하여 추진시스템의 성능에 주요한 영향을 미치는 주 설계인자의 분석을 수행하였다. This paper presents design of the linear propulsion system of a high-speed (200km/h) dynamic tester for catenary-current collection. Among various propulsion systems, a permanent magnet linear synchronous motor is chosen for need of high acceleration force. The design is performed by the equivalent magnetic circuit method and verified by the finite element method. In addition, analysis of the main effects of various design variables for performance of the propulsion system has been done by using simulation-based DOE method.

This paper aims to review the basic conditions in designing the de-icing system of the loop current type in AGT 3rd rail system. The loop current type is defined as melting ice/frost on the rigid conductor by Joule’s heat generated by large current flowing through rigid conductor. A simulation is more cost-, time- effective means than experiments in reviewing the temperature increase in loop current type of de-icing system. To make simulation program, the theoretical backgrounds were reviewed. In accordance with the established theory, simulation program was written in MS-Excel. To verify the accuracy of developed simulation program, current injection experiments in rigid conductor were conducted. Temperature rises at 1700A, 1500A, 1200A were compared with the program. Two(experiment and program) results were fairly good agreed. With the simulation program, case studies were conducted in various assumed conditions, especially in 2m/s wind condition and in 60 minutes current injection, etc. From simulation case study, we deduced followings; 1) The operation of loop current de-icing system is quite safe up to 1700A-60 minutes current injection condition. 2) 30 minutes before commercial operation is proper for the current injection time 3) To obtain the de-icing effectiveness, it is necessary to inject the 1500A or more.

The dropper length calculation method about the normal same encumbrance spans is well known independent to whether the pre-sag is given or not. But the dropper length calculation method for the elevating span which consists in the end area of a tensioning section and normally consists with overlaps is not well known. In this study firstly we investigate the dropper length calculation method about the elevating span whether the insulator is contained in or not we also recognize the effect of dropper length due to the change of the take-off point. Secondly we very this calculation method with a catenary sample data and check again with Gyeongbu HSL design data.

In this study, the relation between the rotation which are usually caused by the creep of the contact wire, the bar geometry and the forces(wire tensions) for the triangle-shaped distribution bar and straight-shaped one in dependent tensioning device system is reviewed. According to the result, a rotation of distribution bar in triangle-shaped one modifies the distribution of the tensions between the three wires hooked in a distribution bar. On the contrary, a rotation on the straight-shaped one leads to no tension distribution change. Therefore, to use the straight-shaped distribution bar instead of triangle-shaped one is recommended. In addition, the design contents of the distribution bar which will be used in electrification of Gyeongbu line are described in this paper.

300km/h 속도로 주행하며 검측할 고속 검측차용 궤도 검측 모듈을 개발함에 있어서 목표 성능을 적절하고 명확히 수립하는 것은 기본적이며 중요한 일이다. 궤도 검측 모듈은 보다 하위 단위로는 궤도 틀림 검측 모듈, 레일 마모 및 프로파일 측정 모듈, 레일표면 및 침목, 체결구 결함 탐지 모듈 및 선로 순회 점검 모듈로 구성된다. 본 논문은 각 세부 모듈 레벨에서 개발 목표가 되는 기준으로서, EN13848-2를 비롯한 국제 규격, 우리나라 유지보수 지침 및 앞으로 경쟁 상대가 될 타 해외 선진 검측 장비 제작사들의 사양을 검토하고 벤치마킹하여 수립한 궤도 검특 모듈 개발 목표 성능에 대하여 기술한다. It is basic and important works to establish the target performances in the project of developing the high-speed(300km/h) track measuring & inspection modules. The track measuring & inspection modules is consist of, as a unit component, the track geometry measuring module, rail profile measuring module and rail surface/sleeper/fastener inspection module. This paper describes the performances, as a developing targets of the track measuring and inspection modules, established by reviewing the EN13848-2 and Korea’s maintenance regulations, and by bench marking the already developed oversea’s products which will be competitors of ours in the future.
