摘要

采用非接触式声发射(AE)监测系统，研制了疲劳裂纹扩展监测系统。首先对飞机弯曲疲劳试验过程中产生的声发射信号进行监测。在疲劳寿命比约为0.5之后，声发射产生率增加。声发射信号的最大振幅与裂纹扩展的趋势相似。然后比较了平面和弧形表面的传感器灵敏度。当样品表面平坦时，灵敏度提高。采用平面棒材试样进行旋转弯曲疲劳试验的声发射监测。从疲劳寿命比0.715开始，裂纹产生后声发射产生率增加。在旋转弯曲疲劳试验中，与圆弧面试样相比，平面试样在疲劳寿命的早期阶段检测到声发射信号。使用非接触式声发射监测系统可以在早期阶段检测旋转部件的疲劳裂纹。

Development of Non-Contact Fatigue Crack Propagation Monitoring Method Using Air-Coupled Acoustic Emission System

A monitoring system for fatigue crack propagation was developed using a non-contact acoustic emission (AE) monitoring system. The AE signals generated during the plane bending fatigue test were first monitored. The AE generation rate increased after approximately 0.5 of the fatigue life ratio. The maximum amplitude of the AE signals increased with a tendency similar to that of the crack propagation. The sensor sensitivities for the flat and arced surfaces were then compared. The sensitivity improved when the specimen surface was flat. The bar specimen with plane surfaces was used for the AE monitoring of the rotary bending fatigue test. From 0.715 of the fatigue life ratio, the AE generation rate increased after crack generation. The AE signals were detected at an earlier stage of the fatigue life in the flat surface specimen compared with the arc surface specimen during the rotary bending fatigue test. The detection of fatigue cracks in the rotary component at an early stage was possible using a non-contact AE monitoring system.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
