摘要：

The mode shape coupling characteristics of structural-acoustic coupled system were introduced. Typical structures and acoustic modes were selected to calculate and analyze the distribution features of coupled system's natural frequencies. Then the judgment criterions for the domination features of coupled frequency were discussed and verified. Based on the judgment criterions, the domination features of coupled system's natural frequencies were deeply analysed. The frequency coupling mechanism of structural-acoustic coupled system was revealed.
