    RESEARCH ON GUIDED WAVE DETECTION METHOD BASED ON Duffing OSCILLATOR AND THE TRADITIONAL METHOD

    Published 2024-01-01
    “…In recent years,ultrasonic guided wave technology has been widely used in nondestructive detection of long distance pipelines due to its advantages of short detection time and wide detection range.In order to further improve the recognition accuracy,a new detection method that combines the theory of cross correlation and wavelet transform with Duffing oscillator system was proposed.The collected signal was pretreated by cross-correlation and wavelet transform,and then input into Duffing system for detection.The results of numerical simulation show that the hybrid measurement method based on the combination of traditional method and Duffing oscillator,can reduce the detection signal-to-noise ratio to-38.4 dB,which is lower than the detection result when Duffing vibrator is used alone-23.9 dB,greatly improving the defect detection accuracy and sensitivity.The research results are of great significance for extending the detection range of an ultrasonic guided wave and improving the detection sensitivity of small defects in practical engineering.…”
