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,得出管阵列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。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-fidd were obtained by calculating field point. The resuits are meaningful in practice to both the development and application of sonic scot cleaning.
