| Abstract: | With the numerical simulation method the muffler performance changes with and without glass fiber materials were analyzed based on the establishment of three-dimensional model of the muffler. At the same time, the influences on entire muffler performance were also analyzed with the changes of glass fiber＇s diameter,density and both of them. The results show the glass fibers can significantly improve muffler performance,and the changes of glass fiber＇s diameter and density have noticeable influences on muffler performance. |
