摘要
对于铁磁性材料,当频率较低时,利用磁致伸缩力可实现超声波的激励;利用压磁效应可以实现超声波的接收。对于钢板导波检测,设计出导波模式单一的换能器是电磁超声检测成功的前提条件。利用钢板中SH型导波传播规律,本文提出了一种新的电磁超声换能器优化设计思路。实验证明按该思路设计的电磁超声换能器较好的实现了单一导波模式的激励、接收。
For ferromagnetic material, the transmission of acoustic wave can be implemented by using magnetostrictive force and the reception of acoustic wave can be implemented by using Piezomagnetic effect in low frequency. For the steel plate guided wave inspection, it is prerequisite to design a transducer that can transmit and receive a pure mode guided wave. In this paper, a new optimization design method of electromagnetic acoustic transducer is proposed by using the shear horizontal guided waves propagation in steel plate. The experimental results show that the electromagnetic acoustic transducer designed according to this method is better to implement the transmission and reception of a pure guided wave mode.
