Prediction of Muffler Transmission Loss and Shell Noise by a Coupled Structure-Acoustic Model

Abstract:

Based on the vibration-acoustic analysis software VA One, a fully coupled structural-acoustic muffler FE model and a muffler cavity FE model are built. Then, a comparison is drawn between transmission loss of the coupled FE model and the cavity FE model, which demonstrates that the structure vibration has a big influence on the prediction of acoustic performance of muffler. Besides, radiated noise by muffler is calculated in this paper, which can provide a reference for the designanalysis and improvement of a muffler.
