| description abstract | Nonlinear and non-stability car impact signal processing method was studied, and time-frequency for multi-resolution was analyzed. The resolution “auto-zoom” was analyzed and time-frequency was allocated for complex instantaneous non-stability signal using Wavelet Transform (WT) theory, the local character and variation trend was indicated, the essence and rule was discovered. By transforming the original signals of car impact wavelet in db4, the trend curve and series detail curves was gained. The logical of time-frequency allocation is clarity. It will be an advantage for analyzing time sequence and events in impact course. | |
