摘要/Abstract

摘要： 结构健康监测是飞行器安全运维的一个重要环节，传感器作为结构状态信息感知的最前端，对结构健康监测至关重要。针对现有压电材料在选材范围和服役温度及环境保护方面受到诸多限制，以悬臂梁结构为例，探究挠曲电传感器及其阵列在结构健康监测领域的应用。首先，基于挠曲电传感器在悬臂梁结构的传感原理，推导挠曲电传感器悬臂梁结构曲率测量的频响函数，并通过试验验证了挠曲电传感阵列用于曲率模态测量的有效性。然后采用柔性电子工艺，设计并制备一种柔性可拉伸的挠曲电传感阵列。最后，开展悬臂梁监测试验去评估传感阵列的损伤识别能力，结果表明，归一化的模态挠曲电信号差可以实现裂纹数量与位置的识别。该工作为结构健康监测提供了一种新的途径，拓展了挠曲电效应的应用范围，对挠曲电走向飞行器结构健康监测具有重要的指导意义。

Abstract: Structural health monitoring is an important link in the safe operation and maintenance of aircraft, and sensors, as the forefront of structural state information sensing, are crucial for structural health monitoring. Aiming at the existing piezoelectric materials, which are subject to many limitations in terms of material selection range and service temperature as well as environmental protection, the application of flexoelectric sensors and their arrays in the field of structural health monitoring is explored by taking the cantilever beam structure as an example. Firstly, based on the sensing principle of flexoelectric sensors in cantilever beam structure, the frequency response function of flexoelectric sensors for curvature measurement in cantilever beam structure is derived, and the effectiveness of flexoelectric sensing array for curvature modal measurement is experimentally verified. Then a flexible and stretchable flexoelectric sensing array is designed and prepared by using a flexible electronic process. Finally, cantilever beam monitoring experiments were carried out to evaluate the damage identification capability of the sensing array, and the results show that the normalized modal flexoelectric signal difference can be used to identify the number and location of cracks. This work provides a new way for structural health monitoring, expands the application range of flexoelectric effect, and has important guiding significance for flexoelectric toward structural health monitoring of aircraft.
