  1. The main achievements are as follows : the theory models of defect mfl field are set up ; based on the magnetic dipole model and finite element model, the distribution of defect mfl field is simulated in the dissertation ; the component of flux density ( magnetic filed ) parallel to the surface of pipe is detected by a circumferential array of hall probes ; the factors including defect geometry parameters, defect surface angle and shape, pipe material, field intensity, vehicle velocity, background magnetization, operating pressure and remanent magnetization and so on influence the mfl signal characteristics

    採用霍爾元件作為缺陷漏傳感器,獲得管道軸截面漏場切向分的漏信號;研究了缺陷外形尺寸、缺陷和形狀、管道材質和化強度、檢移動速度、管道背底場、管內壓力和剩對漏信號的影響。提出了各通道增益放大、各路漏信號偏離調整、波形微分、數字濾波和平滑等漏信號預處理方法;分析了等空間采樣的漏信號轉換為等時間采樣信號的必要性,研究了漏信號的小波去噪方法。
