Time-Frequency Response Analysis of the Vertical Dynamics of Track-Vehicle Systems Based on EEMD |
摘要 |
We studied the time-frequency character of the signal of track-vehicle system dynamics based on EEMD (Ensemble EMD). We got the time-frequency distribution of track irregularity and the character of short-wave track irregularity. We also deduced the trans |
