摘要：

为提高电磁超声传感器换能效率,对电磁超声横波传感器的线圈背板进行了优化设计。首先通过实验方法研究了线圈背板厚度对超声信号的影响,然后通过有限元仿真软件对采用羰基铁粉作为线圈背板时的磁场分布进行了仿真,最后通过实验比较了线圈背板优化前后横波传感器的信噪比和提离距离。结果表明:电磁超声横波传感器中线圈背板的最佳厚度为1.5~2.0 mm;采用长度和宽度尺寸与线圈工作区域相同的羰基铁粉作为线圈背板能显著增加传感器工作区域的磁场强度;与采用非导磁性材料作为线圈背板相比,采用优化后的羰基铁粉背板可使传感器的信噪比增加约1倍,提离距离增加约1 mm。

Abstract:

To improve the energy conversion efficiency of electromagnetic acoustic transducers (EMATs), the coil backplane of the EMAT is optimized. First, the influence of the coil backplane thickness on ultrasonic signals is evaluated via experimental research. Then, the carbonyl iron powder plate is selected as the coil backplane and its influence on the magnetic field of the sensor working area is analyzed via finite element simulation. Finally, the performance of EMATs before and after optimization is compared using experiments. Results show that the optimal thickness of the coil backplane is 1.5~2.0 mm. Moreover, the use of the carbonyl iron powder plate with the same size as the coil working area of the coil backplane can improve the transduction efficiency of EMATs. Compared with the sensors that use nonmagnetic materials as coil backplanes, the SNR of the optimized sensors doubled and the working lift-off distance increased 1 mm, respectively.

Key words: EMATs, bias magnetic field, coil backplane, carbonyl iron powder
