KTX 산천 동력차의 주행 시험 중 진동 특성 연구

초록

It is essential for the high-speed train technology to improve the core technology and speed. KTX-Sancheon, the Korean high-speed train, was developed by our own technology, and gives commercial service with 300km/h. To give more comfortable service to customers, it is important to reduce the unnecessary vibration and noise. It this paper, we measured the vibration on the several position of power car during the test run. And we analyzed the vibration characteristics of the power car of KTX-Sanchoen during the test run. The results will be used to improve the efficiency of KTX-Sanchoen to give the good commercial service.
