摘要
应用全局弱式无网格方法求解消声器的横向模态,使用模态匹配技术求解其传递损失。计算了圆形穿孔管阻性消声器的横向模态和传递损失,计算结果与解析方法和有限元方法计算结果吻合较好,且节省计算时间。
The transversal modes of silencers are extracted by using the global weak-form mesh-free method（MFM）,and the transmission loss（TL） is calculated by using the mode matching technique. The transversal modes and TL calculation results of a circular perforated dissipative silencer are presented to validate the computational accuracy and the efficiency of the proposed technique.
