The approximation analysis result of band dipole model is obtained on the basis of the theory of mfl. the electromagnetic distribution feature of the defect in the steel panel is studied by means of simulation. the leakage magnetic distribution of the two defects and four defects plural and the defects in the column differently in the width are also assayed. conclusions that factors affecting flaw magnetic leakage to the panel also affect the column and magnetic leakage bx should be the feature of the flaw identification to several flaws are drawn
在對漏磁檢測原理進行詳細介紹的基礎上,得出了帶偶極子模型的近似解析解,並以有限元數值模擬分析為主要手段,以鋼板上缺陷為對象,分析了各因素對缺陷漏磁場產生影響的不同規律,同時模擬分析了板上平行的兩條裂紋,四條裂紋以及
柱體上寬度不同時的裂紋的漏磁場分佈特徵,得出結論:影響板上缺陷漏磁場的諸因素會對
柱體上缺陷漏磁場產生同樣的影響;對于多條裂紋,宜用漏磁分量bx作為缺陷識別的特徵量。
