차세대고속열차 차량시스 성능예측 및 성능검증 체계 개발

Korean Train Express (KTX) has been commercially operating and achieving elevation on transport capacity since 2004. And HSR-350x was developed and succeeded in testing of running over 350㎞/h. The new high-speed train development project, HEMU-400x project, has started since last year. To develop the train system, it is important how we progress the configuration of the system, design, manufacturing and test verification. The authors devised the performance estimate and verification process of the HEMU-400x and the project is peformed following the developed processes.
