筋板结构是工程中常见的一种结构形式,其隔声特性一直是科研人员关注的热点。运用实验和两种不同的仿真方法,对单板和加筋后的筋板结构的隔声量进行对比分析,并得到中频段适合梁板组合结构隔声量分析的仿真建模方法。
觔闆結構是工程中常見的一種結構形式,其隔聲特性一直是科研人員關註的熱點。運用實驗和兩種不同的倣真方法,對單闆和加觔後的觔闆結構的隔聲量進行對比分析,併得到中頻段適閤樑闆組閤結構隔聲量分析的倣真建模方法。

Beam-stiffened plate structures are widely used in engineering. Researchers have been paying great attention to their sound insulation properties. In this paper, the sound transmission loss of a single plate and the beam-stiffened plate structures are investigated experimentally and numerically. Discussions are then made on the acoustic properties modeling of the beam-stiffened plate when the structure contains typical mid-frequency behaviors.
