管道超声导波检测专用探头的研制

Development of a Special Transducer used in the Pipes′ Detection with Ultrasonic Guided Waves

结合常规超声探头的研制技术,根据检测对象管道的特殊性,从敏感元件、背衬材料、保护层以及外型等各方面详细介绍了一种管道超声导波检测专用探头的研制过程;利用这种探头分别在板和管中进行了激励接收超声导波的实验,结果表明,这种探头能够激励接收超声导波.

This article depicts in detail a kind of guided-waves transducer, used for pipes detection and some relative manufacture techniques of the transducer. Experiments of generating and receiving guided waves on a pipe and a plane with these transducers are carried out. The result indicates that these transducers can effectively generate and receive guided waves.
