结构声场耦合系统声压激励频率响应有限元分析

FEM Analysis of Frequency Response by Sound Pressure Induction in Vibro - Acoustical Couple System

在声压激励下对双声腔结构声场耦合系统的频率响应进行了分析,研究了通过弹性隔离膜相互耦合的声腔,在具有峰值声压时的声压分布以及无激励源声腔声压与频率的关系。最后,对两个声腔的声压分布关系进行了研究。

Finite element analysis of frequency response by sound pressure induction in vibro - acoustical couple system of a double cavity coupled by elasticity partition film is studied. The acoustical pressure distribution in acoustical cavity at peak pressure and the rektionship of the acoustical pressure change with frequency change in the responding cavity are disussed. The relationship of acoustical pressure distribution in a double cavity system is analyzed.
