一种用于缺陷定量检测的磁屏蔽式锥形脉冲涡流传感器
A Magnetic Shielded Cone-Shaped Pulsed Eddy Current Sensor for Defect Quantitative Detection
摘要
Abstract
Aluminum alloy materials are widely used in aerospace,pressure vessels,ships and other fields due to their lightweight,high strength,and corrosion resistance.However,long-term service under working condi-tions of load impact and stress concentration makes them prone to cracks,corrosion,and other defects,which increases the risk of structural failure and may even lead to equipment failure.Compared to conventional eddy current techniques,pulsed eddy current(PEC)technology offers the advantage of rich frequency domain com-ponents,and enhancement of PEC sensor performance is a critical requirement for non-destructive testing.The configuration of sensor parameters plays a significant role in the effectiveness of PEC systems.A two-dimen-sional finite element simulation model of PEC sensor is established,and the structural parameters of the PEC sensor,including inner radius,coil thickness,coil height,and coil tilt,are optimized using the orthogonal exper-imental method.The performance of the sensor is then experimentally validated.Finally,machine learning algo-rithm is employed to quantify the depth of groove defects in aluminum alloy plates.The Gaussian process re-gression(GPR)model demonstrated the best performance in predicting defect depth,with a maximum error not exceeding 0.25 mm.关键词
