Abstract: | This paper developed a planar array coil sensor and designed the corresponding test device. The feasibility of crack detection of aluminum plate using the array coils was proved through the simulation analysis. Based on the detection experiments of the pre-cracks on the aluminum plate, multiple sets of experimental data were collected. The variety of methods such as gradient analysis and wavelet transform were used to process the data . The experimental results showed that the method could meet the actual needs of detection and it had high sensitivity to the cracks. |
