基于振动分析的机械结构损伤识别方法综述

A Review of Mechanical Structure Damage Identification Methods Based on Vibration Analysis

机械结构的损伤识别是机械结构健康监测的核心,也是一项具有挑战性的研究课题。基于振动的机械结构损伤识别方法在国内外已经受到广泛的关注和重视,成为世界范围的热点问题。首先叙述了机械结构损伤识别的涵义与一般识别步骤,然后综述了目前较为主流的机械结构损伤识别方法的基本理论、各自的识别优势以及尚待解决的不足之处,最后,简述了目前基于振动分析的机械结构损伤识别方法中尚待解决的一些关键问题。

Mechanical structure damage identification is the core of mechanical structure health monitoring system,it is a challenging research topic in the field of health monitoring.People,both at home and abroad,has paid widespread attention to mechanical structure damage identification methods based on vibration,and it has become a hot point in the world.The meaning and general detection steps of mechanical structure damage identification are described in the paper,at the same time,it reviews the relatively mainstream technology for mechanical structural damage identification methods,including the basic theory of all kinds of methods,the advantages of different damage identification,and their disadvantages remained to be solved.Finally,a brief introduction that the current damage identification methods based on vibration analysis have some key problems yet to be solved and their development trend is made in the paper.
