Variation Trends of the Contact Force between Pantograph-Catenary and Acceleration Behavior According to the Train Running Speed and Driving Pattern in Korean High Speed Train

열차의 운행패턴과 속도에 따른 한국형 고속전철용 판토그라프의 접촉력과 가속도 거동의 변화 경향

The pantograph for Korean High Speed Train was developed and had been evaluating by through 'G7-R&D project for home grown high speed train technology' In this study, in mechanical aspect, the variation trend of contact force between pantograph and catenary according to the train running speed and driving pattern is conducted. A measuring system for current collecting performance and mechanical characteristics is used for this study, developed and installed on the prototype Korean High Speed Train, and physical characteristics were measured while the KHST runs on the test track. Through this study, remarkable trends of variation are found and analyzed from measured acceleration and vertical contact force between the pan head in pantograph and contact wire in catenary system according to the driving pattern and the train raised a running speed up to 300km/h.
