Optimal Design and Experimental Validation of a Pulsed Magnetic Flux Leakage Sensor
摘 要
在铁磁性板材、管道腐蚀、裂纹等缺陷检测方面,脉冲漏磁技术显示了潜在的优势。在对多种不同结构的传感器进行仿真分析的基础上,提出了一种新型励磁结构的脉冲漏磁传感器,减少了背景噪声磁场对缺陷漏磁信号的磁场压缩作用，提高了传感器对缺陷信息获取的准确性，适合于绝缘层或涂覆层下缺陷的检测。研制了新型传感器，并对标准试件进行了测试。试验证明了传感器设计的正确性及有效性。

Abstract
Pulsed magnetic flux leakage(PMFL) technology shows potential advantages in the detection of corrosion, cracks and other defects of ferromagnetic plates or pipeline. A PMFL sensor with new structure was proposed based on the simulation for a variety of different structure sensors. It reduced the magnetic field compression of the background noise to the magnetic flux leakage signal and improved the information accuracy of defects. It was suitable for detecting defects under insulating layer or coating layer. The new structure sensor was developed and the standard samples were tested using it. The experiments validated the optimization of configuration and effectiveness of the new sensor.
