Embodiment 1
[0082] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
Embodiment
[0084] Taking the simulated synthetic signal as an example, the sampling frequency is 100Hz, and the number of sampling points is N=1024. The analytical formula is:
[0085]
[0086] According to the processing method of the present invention, the simulated synthetic signal is input on the MATLAB software platform, such as figure 2 As shown, the time-domain signal of the cable-stayed bridge cable vibration collected under the excitation of the simulated environment. First, do S-transform on the signal, and the obtained time-spectrogram is as follows image 3 shown; then take γ GST = 0.1, Increase the front taper of the window function, and the obtained time-spectrogram is as follows Figure 4 show; will and After replacing the position of , the back taper of the window function can be increased accordingly, and the obtained time-spectrogram is as follows Figure 5 shown. Will Figure 4 and Figure 5 and image 3 It can be seen from the comparison that the impr...
