Abstract

Currently, the major railway industrialized countries, including Korea, are carrying out various studies to expand high-speed rail infrastructure to link the metropolitan area organically and to improve its speed accordingly. Railway system that combines a variety of engineering technology needs a number of research and technology for a new high-speed rail route. Various studies have been performed to improve properties of material, electrical and mechanical properties of railway train according to the increase of the speed in the train. In particular, The current collection performance between the electric railway vehicle and the catenary system in electric railroad is a standard for determining the operational performance between pantograph and the catenary system of the electric vehicle. The importance of this current collection performance is growing according to acceleration of the speed in the electric railway vehicle. The purpose of this study was to verify the performance in test-bed of 400km/h class catenary system from Iksan to Jeongeup. We analyzed characteristics by measuring the value of the contact wire uplift, strain and acceleration in the catenary. Analysis of the pantograph and current collection contact force of the catenary in the performance evaluation of catenary is the most important factor. The dynamic properties of these catenary are closely related with electric vehicle speed. In this study, we have verified the performance of the measurement system in the catenary through the startup test in the 400km/h class real test-bed. Various on-site measurement data is expected to help to improve the electric railway speed through the research of dynamic, mechanical and electrical properties of the electric railway catenary.
