摘要
试验模态分析与有限元计算相结合的研究方法是一种实用、可靠的结构动态分析的现代方法。本文着重研究了它的核心和基础．
Dynamic analysis of structure through combining the finite element method with the experimental mode is a practical reliable and effective modern method. This paper has stressed the research of its core and basis,and established the mathematical model of the correlation between the experimental mode and the theoretical mode by the norm 11. 11 1 at first,and then analyzed the correlation of the modes by quantity. This method was proved to be effective by checking the transverse vibration of the cantilever beam.
