- W3038052007 abstract "In the actual project, the structural response often shows the effect of multiple excitation sources because of the random characteristics of the operating environment. So it is difficult for the traditional single source excitation method to meet its actual response characteristics. Therefore, the research on the characteristics of multi-source excitation signal is one of the development trends of mechanical structure detection technology. In this paper, combined with the principle of multi-source excitation and wavelet transform, wavelet packet is used to analyze the multi-source signal. The accuracy of the detection signal can be greatly improved through wavelet packet to reduce the noise of the signal. At the same time, through the comparison between the original signal and the fault signal analysis, we find the superiority of wavelet packet analysis in the structural fault detection." @default.
