模态分析是研究结构动力特性的一种近代方法,是系统识别方法在工程振动领域中的应用,它和有限元分析技术一起成为结构动力学的两大支柱。本文主要是做了环境激励下模态分析方法的一个综述报告。
Modal analysis is a modern method to study the dynamic characteristics of structures. It is the application of the method of system identification in the field of engineering vibration. Together with the finite element analysis, modal analysis becomes the two pillars of structural dynamics. This paper mainly makes a review report of modal analysis under environmental excitation.
