磁子理论
The internal and surface cracks in rolls were detected with magnet as exciting source. Quantitative detection of cracks was realized by the establishment of mathematical model according to magneton theory and quantitative analysis of crack signals based on the piecewise cyclic approximation of neural network.
以磁为激励源进行轧辊表面及内部裂纹缺陷的检测,基于磁荷理论的裂纹数学模型的建立和神经网络的分段循环逼近的裂纹信号定量分析,实现了裂纹无损定量检测。
