Simulation Analysis of Tractor Muffler Noise Reduction Performance
Tractor is an important agricultural machinery,which is widely used in agricultural production.The noise produced by the exhaust pipe during operation affects the health of the operator.The existing muffler is large in volume,and the noise reduction effect of middle and low frequency is insufficient.Moreover,the exhaust gas of the tractor has complex chemical composition and high temperature.In this paper,the structure design of the muffler is combined with theoretical analysis and simulation,and the fluid mechanics analysis of the exhaust resistance is carried out,and a muffler model with good noise reduction effect and small exhaust resistance is obtained.
