在本文中，我们研究了使用高温超导（HTS）SQUID梯度计和磁致伸缩传感器（MsS）对有缺陷的铝管进行超声导波测量，该传感器利用预磁化镍薄板。其中一根管子有轴向缺陷，另一根管子有圆周缺陷。将MsS粘贴在管道圆周上以产生超声波导波，并通过将其转换为磁信号来接收波，并由HTS-SQUID梯度计进行测量。使用MsSs和梯度计进行的导波测量表明，成功检测到了来自两个缺陷的反射波产生的约3.3 mΦ 0 的磁信号。还检测到来自管道上MsS薄镍板的约1.4 mΦ 0 的反射波信号。
In this paper, we investigated ultrasonic guided wave measurements on aluminium pipes with defects using high temperature superconducting (HTS) SQUID gradiometer and magnetostrictive sensors (MsS), which utilized pre-magnetized nickel thin plates. One of the pipes was provided with an axial defect, and the other was provided with a circumferential defect. The MsSs were used by adhering them on circumferences of the pipes to generate ultrasonic guided waves and to receive the waves by converting them into the magnetic signals, which were measured by the HTS-SQUID gradiometer. Guided wave measurements using the MsSs and the gradiometer demonstrated that magnetic signals of about 3.3 mΦ 0 due to reflected waves from both the defects were successfully detected. Reflected wave signals of about 1.4 mΦ 0 from thin nickel plates of the MsS on the pipes were also detected.
