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。Based on the boundary element method, in a single row of the tube as a model, with ANSYS establishing the boundary element model, vibration-noise analysis software SYSNOISE simulated the sound field distribution and directional on the tube surface in different locations of the sound source incentives. Sound field distribution characteristics around the tubes and far-field were obtained by calculated field point. The results were meaningful in practice to both the development and application of sonic soot cleaning.
