摘要: 基于边界元法, 以单排管阵列为模型, 运用 ANSYS 软件建立边界元模型, 用振动—噪声分析软件
SYSNOISE 模拟计算了在不同位置的点声源激励作用下, 管壁表面声场分布特性及指向性; 通过计算场点,
得出管阵2列2周围和远场的声场分布特性图。计算结论对于声波除灰技术的发展及应用均具有实际意义。

Abstract : Based on the boundary element method , using a single row of the tube as a model , the boundary element
model was established by ANSYS software , a point in different locations of the sound source incentives , the sound
field distribution and directional on the tube surface were simulated by vibration noise analysis software SYSNOISE ;
Sound field distribution characteristics around the tubes and far field were obtained by calculating field point. The re
sults are meaningful in practice to both the development and application of sonic soot cleaning.
