R-Bar (Overhead Rigid Conductor system) has been lately used for the speed of over 200 ㎞/h in Europe, while it has been developed and used for the max. speed of 120 ㎞/h in Korea. Because R-Bar has advantages of reduction of tunnel cross sectional area and maintenance, its development for more high-speed is urgent in Korea having many mountain area. Therefore a sensitivity analysis of design parameters for the speed-up of R-Bar has performed in this study. For the analysis, we have developed a program for the prediction of dynamic characteristics between a pantograph and R-Bar. The program was evaluated with the actual test result and a current collection performance according to the parameters such as a distance between brackets, a stiffness of bracket and of R-Bar rail was predicted with the program.

This paper presents study of collection performance according to dropper spacing for catenary. Static characteristics analysis, dynamic simulation, stress and wear analysis for different 5 catenary configurations according to dropper spacing are performed. And collection performance for TGV-Nord catenary system is also analyzed in order to compare and evaluate.

In order to develop a overhead catenary system for the maximum speed of 400 km/h on Honam high-speed line, increasing tension of contact wire, changing dropper distributions, reducing a hard point and etc. should be considered. And it is also essential to develop core components taking account of the increased tension. Therefore we developed a new steady arm for the max. speed of 400 km/h in this study. FEM (Finite Elements Method) analysis was performed to ensure the strength of the arm. An oval shape was applied to the arm, so that 25 % of strength was increased and 9 % of weight was decreased. And a type test according to the code KRSA-3012 was performed to ensure the performance. Fatigue test in KRRI (Korea Railroad Research Institute)’s test-bed was also performed to evaluate its performance. Some section of the Honam High-speed line was constructed with the developed steady arm.

This study presents a development of DeCatS(Detail Design of High Speed Catenary System) which is a software to design high speed catenary system automatically. The program is developed by Korea Railroad Research Institute with the support of KHSR. A process of developing it and a comparison with LEXCAT, in order to demonstrate a preciseness of that, were performed. In the program, decision of H-beam, cantilever fitting, management of materials, automatic drawing and etc. according to input conditions can be accomplished. In this study, especially the program algorithm for the decision of mast was introduced.

In this paper, Multi Mode Receiver Module is designed in one H/W module for Multi-mode Digital Broadcasting. Multi mode means Digital TV, Mobile TV and Digital Radio on the Broadcasting. and T-DMB, DAB(+), ISDB-T and DVB-T standard. Our Module can receive various broadcasting signal such as ISDB-T, DVB-T and DAB. The Multi mode Receiver Module & demuxer was implemented using the one SoC Chip has good performances to receive the multi mode signals as well as standard interface such as SPI, to connect the main CPU Unit.

Increasing tensions of contact wire and messenger wire are essential to construct a test-bed for catenary system in the 400km/h speed on Honam high-speed railway. Because heavy load is applied to a mast due to the increased the tensions of both wires it is required to investigate the strength of the foundation. Therefore in this study the maximum moment of an electric pole under the worst condition was calculated to investigate the strength of the pole foundation on the bridges. The maximum moment database table used in the construction of Kyungbu high-speed railway was referenced to derive the worst conditions and to review the composition of catenary system in the test-bed section. From the results of this study regarding assumptions and calculation process it will be possible to estimate the optimized strength of the pole foundations on the bridges which will be constructed in the future.

Even if tracks cross each other, a train has to maintain a good current collection. Where catenary cross each other, it is called a crossover. Based on the cause analysis for a breakdown accident of pantograph occurred in the crossover on Ansan-line, a theoretical background and recommendation for the installation rule of a crossover are presented in the paper.
