Abstract
To enhance the efficiency and accuracy of defect detection in metal sheets,a non-destructive testing method utilizing a PCB coil based on a rectangular array is proposed.This method begins with the analysis of the pulse electromagnetic eddy current effect and the principle of secondary field integration detection,grounded in Maxwell's equations.By using the COMSOL software,the characteristic pa-rameters of the rectangular array PCB sensing coils are simulated.A 100 cm2 rectangular PCB is designated as the sensing unit,with the detection signal strength serving as the target parameter.The optimization of the PCB coil design involves varying the excitation frequency,number of turns,and lift-off distance to identify the optimal configuration.Subsequently,the optimized coil parameters are applied to simu-late defect specimens,yielding response characteristics for different types of defects.Based on these simulations,a prototype probe and as-sociated signal conditioning circuit are developed.Finally,an experimental platform is established to test samples with various geometric defect characteristics.The results demonstrate that the sensor probe can rapidly and accurately locate defects while effectively identifying different types of flaws within the metal specimens.关键词
