In this study, test standards were developed for performance verification of the high speed(350km/h) rolling-stock. The performance test system consist of three type tests; the component test for core item, the completed car test for combined function & operation and the trial driving test for compatibility & interrelationship with infrastructure.

The conditions for measurement of the interior noise should meet the international standards. However, due to the limitations in test conditions the possible errors in measurement equipment, reliability of the measurement results has been questioned. Hence, the test procedure for the interior noise measurement of KTX vehicles are reviewed and investigated with the reference of international standards. Furthermore, the acceptable tolerance is inspected through the analysis of the factors that influence the interior noise of the KTX vehicle.

The prototype test train(HSR 350X) was developed and is now being tested in R＆D project for developing Korean High Speed Rolling Stock. International cooperative works with German, Japanese, Danish English and Swiss company were done for reviewing the results made by domestic companies and enhancing their design capability. The main results of cooperation are shown in this paper. In addition, some problems and comments issued during cooperation are also represented.

The Honam conventional railroad was already exceseed the limit capacity of transportal ion at some sect ion. Therefore Honam railroad axis needs new high speed railroad line for increasing of transportal ion capacity now. This report was studied about the system technical specification of rolling stock based on new technology or high speed train or advenced countries, KHST and KTX for Honam high speed railroad.

주전력변환장치 및 보조전원장치는 철도차량의 전체 성능을 좌우하는 매우 중요한 요소이다. 두 장치에 대한 다양한 성능을 평가하고 진단하기 위해 상시계측시스템을 구축하였다. 상시계측시스템을 통해 두 전장품에 대한 계측 및 분석을 통한 시험평가와 동시에 완성차시험이나 본선시운전 시험시에 발생할 수 있는 고장원인을 찾아내고 해결하는데 많은 도움을 주고 있다. 본 논문에서는 상시계측시스템을 통해 주전력변환장치, 보조전원장치 등에 대한 고장진단을 실시한 내용에 대하여 연구하였다.

The crash behaviour analysis of KHST is studied. KHST is modeled in 3D using the multibody dynamic analysis program DADS. The forward and side crash behaviour is predicted by tile dynamic analysis model and compared with those of another dynamic model. This study shot's that it is possible to predict tile crash behaviour of the trains in three dimension.
