摘要

基于振动响应传递率的工作模态分析方法是近年来出现的一类新的频域工作模态分析方法。由于振动响应传递率独特的动力学特性，该类方法得到了迅速的发展。从以下三个方面对振动响应传递率及其工作模态分析方法进行综述：振动传递率的概念、振动传递率的估计方法和基于振动传递率的工作模态辨识方法。在对各种辨识方法原理介绍的基础上，分析其特点及其存在的问题。结合多自由度系统模型，采用四种具有代表性的辨识方法对不同激励情况下的工作模态进行辨识，并对辨识结果以及方法的局限性进行了分析比较。

Abstract

The vibration esponse transmissibility based operational modal analysis is a kind of novel frequency domain method proposed in the past few years.Owing to the unique dynamic properties of transmissibility, this kind of method has been developed rapidly.The response transmissibility and operational modal analysis methods were reviewed from three areas as follows: the concept of transmissibility, the estimation of transmissibility and the operational modal identification methods based on the transmissibility.Aiming at a muti-degree of freedom system, four representative methods were applied in the operational modal analysis under different excitation conditions.The identification results and the limitation of these methods were analyzed and compared.
