Carbon fibre composites have a promising application future of the vehicle, due to its excellent physical properties.
Debonding is a major defect of the material.
Analyses of wave packets are critical for identification of the defect on ultrasonic nondestructive evaluation and testing.
In order to isolate different components of ultrasonic guided waves (GWs), a signal decomposition algorithm combining Smoothed Pseudo Wigner-Ville distribution and Vold–Kalman filter order tracking is presented.
In the algorithm, the time-frequency distribution of GW is first obtained by using Smoothed Pseudo Wigner-Ville distribution.
The frequencies of different modes are computed based on summation of the time-frequency coefficients in the frequency direction.
On the basis of these frequencies, isolation of different modes is done by Vold–Kalman filter order tracking.
The results of the simulation signal and the experimental signal reveal that the presented algorithm succeeds in decomposing the multicomponent signal into monocomponents.
Even though components overlap in corresponding Fourier spectrum, they can be isolated by using the presented algorithm.
So the frequency resolution of the presented method is promising.
Based on this, we can do research about defect identification, calculation of the defect size, and locating the position of the defect.
