동북아 철도망 연계를 위한 궤간가변장치 개념설계

A gauge-adjustable system can be used for the fast and safe transportation in the railways with different gauges instead of transshipment or bogie-changing. The system will be necessary to connect the trans-Korean railway with the transcontinental railway effectively. In this paper, the technical requirements for the gauge-adjustable system used for the north-east asia network were studied and the conceptual design of the system was performed. For the purpose, the specification was made and the QFD and TRIZ methods are used.
