This paper discusses the application of finite element method and by means of LMS Virtual lab simulation software to analyze the sound muffler solid coupling characteristics , and caculate many physical quantities. From solid modeling to acoustic performance calculation, the result finite element method could check the data of software simulation, analyzes the muffler noise elimination performance is affected by sound solid coupling characteristics. It provide basis for the performance anlysis of muffler when considering the sound solid coupling ,and to guide after de-noising.
