Localization of Vibrations by Structural Irregularity

本研究的目的是发展基本的理论和方法， 分析了不规则性对近 周期结构 本研究将解决两个主要问题：（1） 制定一个通用的标准，能够预测的发生 强局部化的结构系统，因此，获得一个 物理洞察模式定位;和，（2）调查模式 来自两种类型的近周期结构的局部化--即， 多自由度（DOF）组件系统和单自由度组件系统的装配 和二维多跨连续结构--从而 评估本地化的有害或有益影响， 和被迫的反应。

This research aims to develop the underlying theory and methods for analyzing the effect of irregularities on the dynamics of nearly periodic structures. The research will address two main issues: (1) formulate a general criterion capable of predicting the occurrence of strong localization for structural systems and, therefore, gain a physical insight into mode localization; and, (2) investigate mode localization from two types of nearly periodic structures--namely, assemblies of multi-Degree-of-Freedom (DOF) component systems and one- and two-dimensional multi-span continuous structures--and thereby assess the damaging or beneficial effects of localization for both free and forced responses.
