초록

The prototype of Korean high speed train(KHST), composed of two power cars, two motorized cars and three trailer cars, has been designed, fabricated and tested. In this paper, the body vibration has been reviewed from the viewpoint of the vehicle's safety, the ride comfort and the vibration limits for components and sub-assemblies mounted on the car-body using by analytical method and experimental method. The on-line test of KHST has been carried out up to 260 km/h in the KTX line and the results of the on-line test show that KHST has no problems in the vehicle's safety, the comfort ride and the vibration limits at this speed. And the characteristics of body vibrations has been predicted at 300 km/h and 350 km/h by fitting curve about the measured acceleration signals.
