Abstract
This paper studied the influence of distance between the receiving coil and the excitation coil on eddy current Array Probe based on finite element simulation method, and the reasonable distance interval is given. The results show that if the distance is too far or too close, the amplitude of the signal reflecting defect information will decrease. For the circumferential receiving coil, a close distance will cause large distortion of the waveform, and for the axial receiving coil, if the distance is too close, detected defect location will be advanced.
