| 摘 要： | 基于动力特性的结构损伤检测方法在过去几十年中得到了迅猛发展.该技术的核心思想在于结构的振动特性(比如频率、振型、模态阻尼等)是结构物理参数(如质量、阻尼和刚度)的函数,结构损伤即意味着结构物理参数的改变,而物理参数的改变必然引起结构振动特性的改变.该文介绍了结构健康监测与损伤动力检测方法的涵义、应用现状和分类方法.对基...

| Abstract: | The vibration-based damage identification method has been rapidly developed in the past few decades.The basic idea behind this technology is that the vibration characteristics(such as frequency,mode shape,modal damping,etc.) are functions of the physical properties of the structure(such as mass,damping and stiffness).Therefore,changes in the physical properties will cause detectable changes in the vibration characteristics.In this paper,the meaning,application status and classification of vibration-based da... |
