Railway is a high-traffic area with high publicity. Railway advanced countries use electric railway as electric power as high as train frequency is high. In addition, the speed improvement of electric railway has developed remarkably in long-distance inter-city transportation. With the development of technology due to the increase in the speed of the electric railway, the importance of the reliability of the facilities is increasing due to the diversification of the structures and functions of the facilities. It is possible to operate the system suitable for the demand from the light railroad to the super high speed magnetic levitation train, It is an eco-friendly means of transportation that is used as a power source. A tilting train is being developed to improve speed while using existing lines. With the opening of the high-speed railway in the domestic electric railway, the electric power plan is planned to be completed by 92% in 2020 according to the comprehensive national land plan. Therefore, due to increase of electric power facilities and change of operating environment, there is an increase in electrical and mechanical instability factors to the electric cable, and a social wavelength is large when a fault occurs, and there is a problem that recovery takes a long time. In order to maintain the horizontal line of the catenary line in the line structure of the catenary line, a hanger or a dropper is used to support the catenary line in the form of a curved line keeping the shape of the curved line. Such a hanger or dropper is a constant line The spacing is maintained and the train speed is improved by the number of installations. herefore, when the existing dropper type is changed and applied to the catenary line, the change of the vibration coefficient in the mechanical aspect is examined and the simulation of the catenary vibration characteristic is performed by using the program to predict the change of the vibration of the catenary line. But the vibration characteristics were improved. In this paper, we have investigated the contents.
