摘要

超声导波的几种特性使其在结构健康监测应用中最适合使用。本文旨在模拟这些波在固体中所表现出的行为，并通过实验验证它们在检测铝板各种缺陷方面的有效性，目的是使用压电片有源传感器作为致动器和传感器来监测机身的结构健康状况-主要用于检测断裂或表面腐蚀，以提前警告机身故障。

Ultrasonic Guided Waves for Structural Health Monitoring Applications

Ultrasonic guided waves present several properties that make them optimal for use in structural health monitoring applications. This paper aims to simulate the behaviour exhibited by these waves in solids, and to experimentally verify their efficacy in detection of various defects in aluminium sheets, with an aim to monitor the structural health of airframes using piezoelectric wafer active sensors as actuators and sensors – primarily to detect fractures, or surface corrosion for advance warning against airframe failures.
