    摘要:

    为提高SRM粘结结构脱粘缺陷检测效率,实现大面积快速自动检测,基于漏兰姆波检测原理,提出使用空气耦合超声兰姆波检测技术,对钢/树脂/橡胶粘结结构进行检测研究。使用二维傅里叶变换识别粘结结构中兰姆波模态,从兰姆波波结构出发分析了不同模态兰姆波对于脱粘缺陷的敏感性;使用空气耦合检测系统对不同尺寸缺陷进行定量检测,最后使用概率损伤成像算法对缺陷进行成像。结果表明:兰姆波幅值随脱粘缺陷的尺寸增大而增大,不同兰姆波模态检测灵敏度不同,检测灵敏度高的模态其离面位移更大,使用800 kHz频率的S0模态检测灵敏度高于A0模态,兰姆波成像算法能够快速准确的对脱粘区域进行定位成像。空气耦合超声兰姆波技术能够快速有效地对SRM脱粘缺陷进行检测,提高了检测效率,为非接触超声的实际应用提供了有益探索。

    Abstract:

    In order to improve the detection efficiency of debonding defects in bonded structures and achieve rapid and automatic detection in large areas,air-coupled ultrasonic lamb wave detection technology is proposed to detect and study the defects of steel/resin/rubber bonded structures based on the leaky Lamb wave detection principle.The two-dimensional Fourier transform was used to analyze the Lamb wave modes,and the sensitivity of different modes of Lamb waves to debonding defects was analyzed. The defects of different sizes were quantitatively studied by the air-coupled detection system.Finally,the probability damage imaging algorithm was used to image the defects. The amplitude of the lamb wave increases with the size of the debonding defect.Different Lamb wave modes have different detection sensitivities,and the modal with high detection sensitivity has greater off-plane displacement.Using 800 kHz S0 mode detection sensitivity is higher than A0 mode,the Lamb wave imaging algorithm can quickly and accurately locate the debonding area.Air-coupled ultrasonic Lamb wave technology can quickly and effectively detect SRM debonding defects,improve detection efficiency,and provide beneficial exploration for the practical application of non-contact ultrasound.
