摘要
基于振动的损伤识别方法在过去几十年中得到了快速发展。该技术的核心在于结构的振动特性是结构物理参数的函数,结构损伤也就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。文中介绍了该方法的涵义和应用现状,评述了各方法的优缺点,最后指出了基于振动的损伤识别方法还需进一步解决的问题。
The vibration-based structural damage identification method has been rapidly developed in the past few dec- ades. The basic idea behind this technology is that the vibration characteristics are ~unctions of the physical properties of the structure. Therefore, changes in the physical properties will cause detectable changes in the vibration characteristics. The meaning and application status of vibration-based structural damage identification methods are summarized. For each kind of methods, their strengths and limitations are discussed. Finally, some topics which are worth studying further on vibration- based structural damage identification methods are proposed.
