摘要
在介绍漏磁检测原理的基础上,详细论述了利用有限元法分析缺陷信号的方法以及利用ANSYS对漏磁信号的仿真过程和仿真结果,并对结果进行分析。仿真结果表明,这种方法不仅可以检测到缺陷的存在,而且还能根据缺陷产生的漏磁信号来鉴别缺陷大小形状,判断管道受损程度,对工件的科学合理利用有重要意义。
On the base of introducing the principle of the magnetic flux leakage (MFL) detection,the finite element method based on ANSYS used to simulate and analyze the MFL signal is presented.The results show that the shape parameters of the defect detected can be obtained with the MFL signal, and the piping damaged degree can be concluded. It has significant sense for using the pipeline reasonably.
