摘要
本文将边界元法应用于二维声场分析,给出了以第二类汉克尔函数为基本解的数值计算公式,比较了处理奇异积分的三种不同方法。通过对三种不同边界条件的管道声场和脉动圆柱的辐射声场的计算并与精确解比较,表明了方法是正确而有效的。
In this paper,the two dimensional sound field is analysised by boundary element method and numerical formulars are brought out after three different procedures are compared.The final calculation of the sound fields of the pipes with three different boundary conditions and the sound field rediated from a impulsing cylinder and comp- arision with the theoritical solutions show that the procedures used in this paper are correct and valued.
