Calculation and Optimization of Insertion Loss of a Certain Muffler by Finite Element Method
摘要
Abstract
Considering the insertion loss as an evaluation index and based on ANSYS and Matlab, using the method which get the insertion loss of muffler by simulating the exhaust system to install mufflers(direct simulation method)and another method which get the insertion loss of muffler by calculating four terminal parameters of muffler transfer matrix( indirect simulation method),we calculated the insertion loss of a certain type of muffler A by Finite Element Method( FEM)and improved the structure of it. Finally, the reliability of the improved muffler was verified by experiment. The results show that the transfer matrix method as well as the definition method can be used in prediction of the insertion loss. The improved muffler B shows better performance in insertion loss. The finite element analysis of the insertion loss in the process of muffler design and manufacture were verified.关键词
