摘要

本文的研究重点是利用超声导波和永久附着式压电换能器（PZT）检测和定位用于自主水下航行器的混合金属-复合材料试件（HMCS）中发生的不同类型损伤。根据对HMCS的波结构分析和得到的频散图，选择合适的波激励频率进行数值模拟。因此，在PZT上施加以250 kHz唯一频率为中心的高斯加窗音突发信号，在试样中产生导向超声波。研究发现，除了高阶导波模式外，还产生了沿水-固界面传播的Scholte波模式。在损伤试件中，由于波模与损伤的相互作用，激发波模发生了模态转换。从原始和损伤试样中获得的时域信号的比较表明，从损伤中产生的额外波包在损伤试样中传播。对相应的时域信号进行处理，可以检测和定位试件中的损伤。此外，不同类型损伤的定量表征表明，由于受损区域内的捕获波能泄漏到周围的水中，可能无法准确估计损伤大小。此外，发现传播距离对损伤检测的影响是高度敏感的，这表明为了获得可靠的损伤检测估计，必须同时分析面内和面外波位移。最后，基于Hilbert包络线最大幅值计算的损伤上的波散射表现出方向依赖的特性，在特定的角方向上，波的幅值随损伤尺寸的增大而增大。发现的损坏位置与损坏的物理位置非常一致。对数值模拟中所考虑的所有情况进行了实验，结果表明两者吻合较好。因此，所提出的方法被认为适用于使用超声波和永久附着的高性价比PZT传感器对水下HMCS结构完整性进行非破坏性研究。

Detecting the structural integrity of autonomous underwater vehicles made of hybrid metal-composite plates using ultrasonic guided waves – Simulations and experiments

The present research focusses on detecting and localizing different types of damage occurring in a hybrid metal-composite specimen (HMCS) used for building autonomous underwater vehicles through ultrasonic guided waves and permanently attached piezoelectric transducers (PZT). A suitable wave excitation frequency is selected for conducting numerical simulations based on the wave-structure analysis and dispersion diagrams obtained for the HMCS. Accordingly, a Gaussian-windowed tone burst signal centered at a unique frequency of 250 kHz is applied at the PZT to generate guided ultrasonic waves in the test specimen. It is found that, in addition to the higher order guided wave modes, Scholte wave mode is generated and propagates along the water–solid interface. In case of damaged specimens, mode conversion of excited wave mode is observed because of the wave mode-damage interaction. The comparison of time-domain signals obtained from the pristine and damaged specimens shows additional wave packets emerging from the damage to be propagating within the damaged specimens. The corresponding time-domain signals can be processed to detect as well as locate the damage in the specimen. Further, quantitative characterization of different types of damage reveals that an accurate estimation of damage size may not be feasible due to leaking of trapped wave energy within the damaged region to surrounding water. Moreover, the influence of propagation distance on the damage detection is found to be highly sensitive and reveals that an analysis of both in-plane and out-of-plane wave displacements is mandatory to get a reliable estimate of damage detection. Lastly, wave scattering across the damage calculated based on the maximum amplitude of Hilbert envelope shows a direction dependent behavior and an increase of wave amplitude with increase of damage size at specific angular directions. The locations of damage found are well in harmony with the physical locations of damage. Experiments are conducted for all cases considered in the numerical simulations and a good agreement is observed between both. Thus, the proposed methodology is deemed suitable to investigate the structural integrity of submerged HMCS non-destructively using ultrasonic waves and permanently attached cost-effective PZT sensors.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
