Proposed Fatigue Test Specifications for Electric Railway Overhead Catenary System Droppers at a Maximum Speed of 400km/h

초록

In this study, fatigue test specifications for a dropper at a maximum speed of 400km/h were proposed. The EN50119 comprehensive fatigue test method was used. However, the load applied to the dropper was determined based on the dynamic simulation results between the pantograph and the overhead catenary system. A fatigue test facility in which the proposed method could be performed was also built. The proposed fatigue test specifications and test facility are expected to ensure the safety of the dropper clamp and cable at a maximum speed of 400km/h.
