模态理论的进展

传统模态理论的基本思想，近年来得到进一步发展和完善，并被引伸到非线性结构振动分析、应力应变振动分析等领域中，发展迅速．本文在总结近年来国内外文献的基础上，根据笔者自己的研究，较系统地介绍了线性位移实模态、复模态分析，广义模态分析，非线性结构系统模态分析，应力应变场模态分析等方面的研究情况． 

THE ADVANCES OF MODAL THEORY

in recent years the classic modal theory for linear dynamic systems is in a continuous development and has also been extended to nonlinear structural vibrating systems and strain/stress field vibration analysis. Many important results have been obtained. This paper gives a brief review on the research on displacement real, complex and generalized modal theories of linear vibrating systems, nonlinear modal analysis of structural vibrating systems, strain/stress modal analysis. A list of references is presented at the end of the paper.
