基于温度场模拟的消声器壳体“发黄”现象分析

摘要

根据流体动力学和有限元思想，运用先进的流体分析软件ANSYSCFX对摩托车消声器内部温度场进行数值模拟研究，得到壳体表面温度场的分布情况，找出其与“发黄”现象的联系，进而针对这一问题提出了对消声器内部结构进行优化设计的有效的解决方案。%Based on the theory of fluid dynamics and finite element method, using ANSYS CFX software to numerically simulate the temperature fields in a motorcycle muffler. The results of the analysis suggested temperature distribution of the shell surface of the muffler, and the relations between temperature distribution and the ＂yellowing＂ phenomenon was identified. Furthermore, effective solutions were proposed to solve this problem by optimizing the internal structure of the muffler.
