摘要 本文应用有限元法对抗性消声器内部声场进行了有限元分析。建立了抗性消声器声场有限元分析模型,通过加载、求解以及后处理等对消声器内部声场进行计算分析,获得消声器内部声压级和压力分布情况。通过分析结果可以直观地获取消声器进出管的长度、内插管的长度和直径大小以及穿孔板孔径大小对消声器传递损失和消声性能影响,为消声器的优化设计提供可靠的依据。 In this paper, the sound field of muffler is analyzed by finite element method. The model of reactive muffler sound filed finite are built, then acoustic pressure and fluid pressure distribution in reactive muffler are computed after a series of sound field analysis procedure including loading, solving and post processing. The analytic results show the effects on and acoustic performance directly subject to the length of the outer pipe, the length and the diameter of the internal pipes and hole size in the board. It provides a solid evidences for optimal design of the muffler.
