摘要
根据穿棒法产生的磁场分布和磁介质的磁化规律 ,给出了圆盘边缘柱面上沟槽棱线上磁荷密度和漏磁场的解析表达式 ,计算了它们的数值并画出其空间分布图 ,理论分析与磁粉探伤的经典实验基本一致。
According to the distribution of the magnetic field caused by the threading bar technique and the magnetization law of magnetic medium, the analytic expressions for the linear magnetic charge density along the edges of the slot on the cylindrical surface of a disc and the magnetic leakage field of the slot were given. Their digital magnitudes and spatial distribution were calculated and plotted. Theoretical analysis conformed with the classical experiment of magnetic particle inspection on the whole.
