基于波动理论的结构损伤识别研究进展

Recent advances in structural damage identification based on wave theory:a review

目前人们对于结构的使用安全越来越重视,结构在日常使用或灾后的损伤识别检测也变得尤为重要。近年来国内外对于波在结构中的传播理论进行了深入研究,基于波动理论的结构损伤识别方法也取得了一定进展。文章首先介绍波在介质中的传播以及在各种类型结构中的传播规律和传播特性,其次从基于波传播理论的结构损伤识别、基于Lamb波的结构损伤识别、波动理论和神经网络相结合、波动理论与其他技术或算法的融合4个方面对国内外基于波动理论对结构损伤识别方法的研究成果进行综述。

Nowadays,the use safety of structures has attracted more and more attention,and the damage identification and detection of structures in daily use or after disaster becomes particularly important.In recent years,in-depth research has been conducted on the theory of wave propagation in structures at home and abroad,and certain progress has been made in structural damage identification methods based on the wave theory.This article first introduced the propagation of waves in the medium,and the propagation laws and propagation characteristics in various structures.Then,this paper summarized the research results of structural damage identification methods based on the wave theory at home and abroad from four aspects,i.e.,the structural damage identification based on the theory of wave propagation,the structural damage identification based on Lamb wave,the combination of wave theory and neural network,and the integration of wave theory and other techniques or algorithms.
