강체전차선로 고속화를 위한 설계파라미터 민감도 분석 연구

초록

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.
