Abstract

The finite element modeling of acoustic silencers was presented. The model was developed taking into account factors such as geometry, sound absorbing materials and environmental conditions. The results were excellent for purely reactive acoustic silencers and good for absorptive silencers. A more complicated model for sound absorbing materials and the inclusion of flow was required for more accurate results.

消声器的有限元建模

提出了消声器的有限元建模方法。该模型的建立考虑了几何形状、吸声材料和环境条件等因素。结果表明，纯反应性消声器和吸收性消声器的效果都很好。为了得到更精确的结果，需要一个更复杂的吸声材料模型和包含流动的模型。
