摘要

通过实验结果与仿真结果的对比验证了有限元法预测汽车排气消声器性能的正确性,进而运用有限元法探讨了消声器子结构拼接方式对消声器整体性能的影响,并从拓扑关系角度解释了该影响的理论成因;然后在总结消声内部连接关系的基础上,结合图论的相关方法提出了一种可以直观展示消声器内部连接关系的拓扑图,并根据不同功能结构在拓扑图中表现出的不同特征规律得出了消声器子结构划分的具体方法。最后通过实例验证了该拓扑图在判断消声器内部连接关系和划分消声器子结构方面的工程适用性。

Abstract

The correctness of the finite element method (FEM) to predict vehicle exhaust muffler’s performance was verified through comparing test results and simulation ones. The effects of the muffler’s substructure connection mode on its whole performance were discussed using FEM. The theoretical cause of these effects was explained from the view point of topology. A visual topology graph was proposed to intuitively reveal a muffler’s inner connection relations based on the graph theory and summarizing connection relations inside the muffler. The specific method for dividing the muffler substructures was gained according to different functional structures’different features indicated in the muffler’s topology graph. Finally,actual examples were used to verify the engineering applicability of the proposed muffler topology graph.
