结构界面约束的模态参数变换方法

The Transformation Methods for Modal Parameters of Structure with Constrained Interfaces

试图对以试验模态分析的结果作为参考基进行不同边界条件之间的结构模态参数的变换问题进行一些探讨。给出了利用自由界面的结构模态参数得到固定界面和弹性连接界面的结构模态参数的计算方法，并讨论了参数变换方法应用的有关问题。

This paper attempts to doing some explorations for the problem of transforming the modalparameters between same structure with difference boundary conditions based on the results of experimentmodal analysis. The computation methods for obtaining the modal parameters of structure with fixed orelastically constrained interfaces through ones of structure with free interface are given. Some questionsconcerning the application of the parameter transforming methods are discussed.
