摘要
运用有限元分析软件ANSYS对某消声器内部声场及流体行为进行有限元分析。以定性分析为目标,将理论计算结果和实验结果进行比较,表明理论计算结果是正确的。为类似问题的分析提供理论方法。
Finite element analysis software ANSYS was applied to analyze the acoustic field and fluid behavior within a muffler. In the viewpoint of qualitative analysis, the computation output was com- pared with experimental data. It shows that the theory of computation is correct. This paper provided a method for analyzing analogue problems.
