차세대고속열차 본선 시운전 성능평가 방안에 대한 연구

Korean Train Express (KTX) has been commercially operating and achieving elevation on transport capacity since 2004. And the first hish-speed prototype test train, HSR-350x, was developed and succeeded in testing of running over 350㎞/h. Now KTX-II based on HSR-350x was started in service run. The new high-speed train development project, HEMU-400x project, has started since 2007. The protype train is being designed and manufactured. After the train are developed completely, it will run on the commercial line and will be test to verify the estimated performance. The authors devised the performance evaluation method and process of the HEMU-400x prototype system. And we introduce the definite performance test items and the method to vitrificate them in this paper.
