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.

Key words

Structural-acoustic coupled system / Mode shape coupling coefficient / The distribution feature of coupled frequency / The domination feature of coupled frequency.
