摘要

摘要：给出结构和声腔耦合系统的振型耦合特点，选择几阶典型结构声腔模态，计算分析耦合系统固有频率的分布特性；分析论证耦合系统固有频率的主导特性判断准则；基于该准则深入分析耦合系统固有频率的主导特性，从而揭示结构声腔的频率耦合机理。

Abstract

Abstract: The mode shape coupling characteristics of structural-acoustic coupled system is given out. Special structure and acoustic modes are picked out to calculate and analyze the distribution features of coupled system natural frequency. Then the judgment rules of the domination feature of coupled frequency is discussed and verified. Based on the judgment rules deep analysis of the domination features of coupled system natural frequency is done. Finally the frequency coupling mechanism of structural-acoustic coupled system is achieved.
