摘要: 作为新兴的无损检测手段,非线性超声混频检测技术因其具有空间选择、波形转换、频率可选、方向可控等独特优势,近年来得到了广泛的关注。该技术是利用两列波在介质中的非线性相互作用特性,实现对材料力学性能的无损检测。研究表明,非线性超声混频检测技术可有效检测出诸如材料塑性变形等早期力学性能退化情况,并能实现对缺陷的定位。由于该技术对材料损伤检测的独特优势,近年来国内外许多学者做了大量研究工作,并取得一系列成果。但目前对该技术的综述性工作还相对较少。为更好地理解非线性超声混频检测技术,从共线混频检测和非共线混频检测两个方面,综述该技术在材料无损检测领域中的研究现状及进展,阐述国内外学者对该技术的研究成果。对该技术的发展趋势进行展望,期望为后续非线性超声混频检测技术的进一步研究和应用提供参考。

Abstract: As a new non-destructive evaluation method, the nonlinear ultrasonic wave mixing technology has attracted much attention in recent years due to its unique advantages, such as spatial selection, waveform transform, frequency selection and controllable direction. In wave mixing technique, the non-destructive evaluation of mechanical properties of materials are realized by using the nonlinear interaction characteristics of two waves propagating in the medium. The results show that this technology can detect the degradation of mechanical properties at its early stages, such as plastic deformation; and can realize the localization of defects. In recent years, a lot of research works have been conducted and quite many achievements have been obtained in the field of wave mixing technology. However, reviewing papers about the advances in the research of nonlinear ultrasonic wave mixing detection technology in non-destructive evaluation are quite limited presently. To better understand the nonlinear ultrasonic wave mixing detection technology, the recent theoretical, numerical and experimental advances of this technology is reviewed, mainly focusing on the collinear wave mixing detection and non-collinear wave mixing detection methods. Finally, the future research emphasis and development trend of this technology are presented and discussed. It is expected to provide a reference for further research and application of nonlinear ultrasonic mixing detection technology.

Key words: non-destructive evaluation, nonlinear ultrasonic, wave mixing
