摘要
本文采用边界单元法,进行任意二维稳定声场的数值计算。通过两个算例的数值解与精确解的比较,说明边界单元法是求解工程声学问题的一种有效方法。编制的程序可用于任意二维稳定声场的分析。
Numerical calculation of arbitrary two-dimensional steady sound field is developed with boundary element method, and used to obtain radiated field generated by a uniform pulsating cylinder and an oscillating cylinder. Numerical solutions of two examples are compared with analytical ones, illustrating the more effectiveness of BIE method in engineering acoustics. Program compiled is applicable to the analysis of arbitrary two-dimensional steady sound field.
