STUDY OF TILTING TRAIN PANTOGRAPH CONTROL SYSTEM FOR EMU

초록

Tilting trains are now an established feature of railway operations throughout the world. For intercity traffic, tilt provides operators with increasing speeds, and therefore enhanced competitiveness, on existing routes where insufficient traffic or a lack of funds precludes the construction of a dedicated new high-speed railway. Pantagraph is a device to deliver the electric current from catenary and that is installed on the roof of EMU. The design purpose of pantagraph is the delivery of continuous and consistent electric current in the circumstance of high speed and other various environment. As the train speed faster, the problems of de-wiring discontinuing the current, abrasion of catenary and current collection shoe of pantagraph, and moise are became the prominent figure. Also, as the project is oriented for the high speed tilting EMU, the pantagraph should be developed in tilting pantagraph type.
