A Study on the Contact Force between Catenary and Pantograph in Duplicate KTX-II Operation

Abstract

Electric railway system driving the electric cars using power from catenary has been secured by performance of stable tracking between pantograph and catenary. The performance of the power collecting of pantograph is the one of the most important skills for high-speed train speed. The first Korea high-speed train(KTX) is 20 cars in one train set. In the meantime, collecting capability of single pantograph collector at one train set was confirmed through evaluation of the performance and the stability test. However, more research is needed to build for a stable collecting capability of cou-pled Korea's KTX-II High-speed system which is developed in Korea. In this study, actual vehicle test of coupled KTX-Sanchon was made to analyzing the data presented by the dynamic nature of catenary and pantograph, and the interface characteristics.
