摘要:
基于漏磁检测的铁磁材料磁记忆损伤检测中，微弱的漏磁信号会导致对细微缺陷和损伤的漏检。该文提出一种铁磁材料漏磁测量仪，通过高压脉冲信号对铁磁材料进行激励以增强磁场，采用4组按照纵向、横向和法向3个自由度安装的传感器同时对磁场信号进行连续检测。实验表明，此测量仪相比于普通测量仪检测效率提高了4倍；无损伤区域漏磁信号强度变化微小，损伤处漏磁信号强度增加了1.9倍以上，提高了测量精度和效率。
Abstract:
Weak signals will cause the omission of minor defects and injuries in the magnetic memory detection(MMD) for ferromagnetic materials,which is based on the detection of magnetic flux leakage. In this paper,a magnetic flux leakage measuring instrument for ferromagnetic materials is presented, which stimulates the ferromagnetic materials magnetic field with high voltage pulse signal,and four sets of sensors are used to continuous detect of magnetic field signals, which are installed in three degrees of freedom by longitudinal,horizontal and normal. The experiment results show that the efficiency of this measuring instrument is four times more than the normal measuring instrument, the variation of magnetic signal strength is small in undamaged area, and the leakage of magnetic signal in the damage area is almost doubled,and the efficiency and accuracy of testing is improved.
