引入近场声发射 (AE) 波束形成方法来定位因飞机结构损坏而产生的 AE 源。在薄钢板的不同区域进行了一系列铅笔芯断裂测试，以验证 AE 波束形成方法的有效性。结果表明，所提出的波束形成方法能够有效地定位声发射源。结果表明，AE波束形成方法是检测飞机板结构损伤位置的有效工具。
A near-field acoustic emission (AE) beamforming method is introduced to localize the AE source arisen from damage of aircraft structures. A series of pencil lead break tests at various regions of a thin steel plate are conducted to validate the effectiveness of the AE beamforming method. The results show that the proposed beamforming method is able to efficiently localize AE sources. It is demonstrated that AE beamforming method is a useful tool to detect the position of damage of aircraft plate structures.
