摘　　要：根据设计的磁场检测探头以及所建立的分析模型和各类缺陷模型,对子午胎钢丝帘线的典型缺陷进行磁场有限元计算分析。分析表明,可用磁极下与钢丝帘线层垂直的磁感应强度分量的变化来辨识帘线的缺陷。从理论上证明了该方法的可行性,为研制检测钢丝帘线带束层以及子午胎质量的新型检验机奠定了基础。The probe for detecting magnetic field was designed and the analytic model and various kinds of defect models were built to analyze typical defects of steel cord in radial tire with finite element analysis (FEA) of its magnetic field. The analysis showed that the defect of steel cord could be recognized by the variation of magnetic induction strength perpendicular to steel cord layer under the magnetic pole. It was theoretically proved that inspecting typical defect of cord with FEA was feasible, which made a good base for the research of a new trial system in detecting steel cord beam layer and radial tire quality.
