초록

In winter season the driving test of the KTX showed the excessive vibration in the tail cars. In this paper, the measured KTX vibration data during test run is analyzed in time and frequency domain. And the numerical simulations using ANSYS and ADAMS are done on the basis of the experimental observations. The results show that 0.6Hz of the tail car motion is due to the natural mode of car combination of the KTX.
