Abstract
The Korean High-Speed Train(HSR 350x) had been developed by through 'G7-R&D project' in 1996-2002, and has been testing and evaluating it's reliability on the high-speed line until now. A number of core equipments designed and developed by using domestic technologies were boarded on the HSR 350x. In order to verify the performance of HSR 350x and core equipments such as traction system, brake system and pantograph, sophisticated testing and evaluating procedures should be considered and applied. In this paper, the tested and analysed results about the dynamic characteristics of HSR 350x pantograph are introduced in a view point of the mean contact force and it's variation trend, criterion of current collection, and up-lifting of contact wire when the MSR 350x running up to 350 km/h. Through the test and evaluation, we verified that HSR 350x pantograph had an excellent current collection performance and good dynamic characteristics as it had been designed.
