储罐底板表面缺陷漏磁场数学模型建立

Establishing the mathematics model of tank bottom corrode disfigurement throughout themagnetic leakage theory

本文通过实地现场测量罐底腐蚀缺陷,对罐底实际缺陷进行了统计分类,简化了缺陷形状,并用漏磁场理论进行了分析,建立了罐底存在的点状腐蚀缺陷、圆柱状腐蚀缺陷、矩形槽状腐蚀缺陷的数学模型,并在最后提出了求解实际缺陷漏磁场的方法。

Through road-testing tank bottom corrode disfigurement, in this text we count and classify all disfigurement and simplify the form of the disfigurement . Then we analyze the disfigurement throughout the magnetic leakage theory and set up the mathematics model of some corrode disfigurement such as dot form, cylinder form and rectangle form in tank bottom. Finally we put forward to the method about solving the real the magnetic field of the disfigurement.
