摘要
根据空腔声学的离散方程式，讨论了三维空腔的各种边界条件及其处理方法，运用流固耦合的空腔声压广义有限元方程，进行了实例计算。
From the discrete equation of cavity acoustics,this paper discusses various bounding conditions and the methods to treat them as a three-dimensional cavity.By using the generalized finite element equation of cavity acoustic pressure with acoustic fluid-structural coupling,the numerical calculation for a practical example is conducted.Therefore,the basis is provided for the optimization for the structure of a cavity and the distribution of the vibration source in it.
