摘要
为了给实际检测系统中缺陷的定量研究提供理论指导,基于所研究系统,建立了针对低频涡流磁场探伤的有限元模型,推导出仿真分析必需的计算公式,最后给出仿真结果。研究结果为实际检测系统中缺陷的定量研究方面提供了有价值的参考。
To give some advice of quantitive research of defects in actual inspection system, baaed on the research system, a finite element model is built up for low frequency eddy current magnetic field defects test. The necessary simulation analysis formulation is deduced. In the end, the simulation results are given in figure. The result will provide a valuable reference for quantitive research of defeacts in actual inspection system.
