高速漏磁检测的二维缺陷轮廓重构
2D Defect Profile Reconstruction of High-speed Magnetic Flux Leakage Testing
摘要
Abstract
Considering the key techniques and difficulties of defect visualization in high-speed MFL testing, to preprecesses defect MFL signals through lifting wavelet package method, a theoretic analysis to the influence for MFL signals of the velocity of the sensor in high-speed MFL testing based on electromagnetic field essential theory is given.Present RBF neural network compensation measure which based on regularization theory, and gained the velocity invariance response of the defect MFL signals through net mapping.And RBF networks which optimized by ant colony algorithm for two-dimensional inversion of defect MFL signals is applied to implements Profile Reconstruction of 2D defect.关键词
