APPLICATION OF NORMAL PANTOGRAPH TO TILTING VEHICLE WITH TECHNICAL MODIFICATION OF VEHICLE SYSTEM

초록

The tilting train technology and reduction of travel time has been carefully investigated by KRRI (Korea Railroad Research Institute). Based on the primary research result from KRRI, tilting pantograph and tilting bogie are considered its core technologies. Due to very complicate operational mechanism and requirement of interface technology between each subsystems of tilting vehicle, tilting pantograph technology is considered most difficult technical field of tilting train development project. In this paper, previous efforts to apply simple tilting pantograph mechanism to tilting system from foreign railway manufacture and operator are briefly introduced with tilting train technical principle. All the technologies have its technical advantage and disadvantages to practically use. Main target of this paper is to eliminate technical difficulties and design effort of tilting vehicle. Vehicle system and its important parts such as coupler, high voltage cable and bogie frame are technically modified to apply regular pantograph to tilting system. Maintenance solution and method of vehicle unit are explained with this system."
