Abstract EN
Ultrasonic testing analysis is a crucial scientific component during the process and interpretation of the ultrasonic detection signal.
Focusing on the ultrasonic testing characteristics, the time-invariant spectral analysis method cannot meet the processing requirements of the detection signal fully.
Thus, S transform, the time-varying analysis method, was introduced into the ultrasonic testing data processing of the concrete structure.
The acoustic wave phase velocity was derived based on the spectrum analysis, and the S transform time-frequency analysis method was established.
Finally, based on the method of concrete experimental data set, studies show that the frequency energy spectrum with S transform can realize flexible and effective identification of defects in the concrete structure.
Definitely, this analysis method can significantly improve the resolution and practicality of ultrasonic testing.
