Boundary Element Method for Fast Calculation of Arbitrary Sound Field Radiated by Vibrating Body

在运用边界单元法离散Ｈｅｌｍｈｏｌｔｚ积分方程的基础上，采用远场近似，提出了一种快速求解任意振动物体辐射声场的数值计算方法。并用该法对实例进行了计算和分析。

In this paper,a method is put forward for fast numerical calctilation of arbitrary sound field radiated by vibrating body by using farfield approximation on the basis of boundary element method for discrete integral equation. This method is used to calctilate and analyze the sound energy of the practical examples。
