摘　　要：针对子午胎钢丝帘线的典型缺陷,用磁场检测法构造检测探头,建立分析模型和各类缺陷模型,进行磁场有限元计算分析。分析表明,检测磁极下与钢丝帘线层垂直的磁密分量变化可辨识帘线的缺陷。分析结果证明了该方法的可行性,为研制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。Based on building the magnetic field probe,the analytic model and various kinds of defect models,the magnetic field at the region of typical defects of steel cord is analyzed by finite element analysis for radial tire.The analysis indicates that the defects can be identified by the change of magnetic flux density component perpendicular to belt under the pole.It is proved theoretically that the method is feasible,which can be used to establish the foundation of developing new type machine for inspecting quality of belt and radial tire.
