介绍了高速漏磁检测中速度效应的基本原理,研究了高速下漏磁信号的变化规律,对基于维纳滤波的信号补偿进行了研究,补偿后的信号可以正确地反映被检测缺陷的参数信息。
The basic principle of speed effect in high speed magnetic flux leakage testing is introduced. The variation law of magnetic flux leakage signal at high speed is studied. The signal compensation based on Wiener filter is studied. The compensated signal can correctly reflect the parameter information of the detected defect .
