摘要
在管道现场检测中,由于检测装置的移动影响,使得从采样记录的漏磁信号波形直接获得缺陷外形的定量描述比较困难.为提高缺陷检测的精度,分析管道漏磁检测中检测仪器运行速度对缺陷漏磁信号的影响,提出一种速度效应补偿方法,通过ANSYS有限元分析软件验证方法的有效性,该补偿方法有利于缺陷的准确识别.
In detecting the mobile device at the scene of the pipeline,because of the impact of testing,it is more difficult for the sample records from the magnetic flux leakage signal wave form to provide direct access to the quantitative description of defects.To improve the accuracy of defect detection.The device velocity influence on magnetic flux leakage in pipeline defects was analyzed in oil-gas pipeline magnetic flux leakage inspection.The compensation method for the velocity influence was put forward.Through ANSYS finite element analysis software, the validity of the method was verified, and the compensation method will help identify defects.
