Abstract

Abstract: The plate remote field eddy current testing technology is not affected by the skin effect, and has great advantages in detecting hidden defects in metal riveting components. For the remote field eddy current testing of metal riveting components of aircraft, a three-dimensional model for detecting hidden defects of riveting components is established, and the shielding performance of different shielding damping materials and combinations of the materials are analyzed. By adopting the detection method that both the excitation coil and the detection coil rotate around the rivet, the defect detection sensitivities when the angle of the excitation coil-rivet-detection coil is 90°, 135° and 180° is compared, and the detection signal characteristics of different defect sizes are studied. The simulation and test results show that it has the best shielding performance when the shielding damping is composed of aluminum and copper, and the remote field area is the closest to the center of the excitation coil. When the distance between the excitation coil and detection coil is 30 mm, the best detection effect is obtained when the angle of excitation coil-rivet-detection coil is 180°. The optimized probe can detect the hidden defects of riveting components with the buried depth of 6 mm and the size of length×width×depth of 5 mm×0.2 mm×1 mm. The amplitude of defect signal corresponds to its volume equivalent relation, and increases with the increase of defect length and depth.

Key words: metal riveting component, hidden defect, remote field eddy current, coil angle, shielding damping
