Abstract： In order to study the vertical acceleration decay laws of ground vibration, the field vibration induced by impetus locomotive CRH2 were measured on the SuiYu ballastless truck. Through establishing the empirical formula of vertical acceleration vibration level decay laws on the basis of least-squares criterion , the analysis shows that the first-order exponential function is better than quadratic polynomial function in the fitting the experiment data. Based on the EMD and HHT, Comparative analysis shows that using Hilbert spectrum to study on the vibration is more suitable for than using that of Fourier spectrum
