The finite element model of diesel engine muffler is established, the noise reduction function of the muffler is studied and tested, the distribution cloud diagram of sound pressure level inside the muffler is calculated, the sound fields at various frequencies are plotted. The change of sound pressure level inside the muffler is tested. After processing, the line spectrum and octave band results of the transmission loss of the muffler are obtained. The acoustic performance of the muffler can be quantitatively determined by synthesizing the results of the sound field distribution and the transmission loss inside the muffler.
Silencer, cloud diagram of sound pressure level distribution, frequency sound field, transmission loss
