Embodiment Construction
[0035] The present invention will be further described below in conjunction with drawings and embodiments.
[0036] Based on the Lorentz force effect, a variable-mode magnetic concentrator type electromagnetic acoustic transducer is designed, and the transducer is used to excite a single-mode A on the aluminum plate. 0 Mode Guided Wave S 0 Modal guided waves.
[0037] The structure diagram of the variable-mode magnetic concentrator Lamb wave electromagnetic acoustic transducer is as follows: figure 1 , where a) the excitation mode is A 0 Schematic diagram of the transducer structure, b) the excitation mode is A 0 Schematic diagram of the time transducer structure; including a NdFeB magnet 1, a class A magnetic concentrator 2, a class B magnetic concentrator 3, and a double-layer variable-pitch folding coil 4 in a flexible circuit board. The detection object is an aluminum plate with a specification of 1000×1000×1 (unit: mm). Figure 6 is the ultrasonic guided wave group v...
