| Abstract: | In this paper,we have had finite?calculation to dynamic structure according to the muffler drawings and the relation parameters.As we have received a disc impedance muffler model set at the entrance of LGA fan by using the optimum design way before the muffler is made so that we can learn preliminary dynamic behavior.It has supplied effective ways. |
