400km/h급 전차선로 곡선당김금구 개발

초록

Increasing tensions of contact wire and messenger wire, changing dropper distribution and etc. should be performed in order to construct a test-bed for catenary system in the 400km/h speed on Honam high-speed railway. And it is also essential to develop a steady arm, bracket, end fitting, dropper clamp, tensioning device and so on for the increased tension. Therefore, in this study the maximum force applied to a steady arm under the worst condition was calculated to develop new steady arm. And through a stress analysis and etc, a new steady arm is designed and developed. From the results of this study regarding calculation process it will be possible to estimate the design of the steady arm which will be developed in the future.
