【摘要】 描述了车用排气消声器的声学性能预测，在前人的基础上新建了两种消声单元的传递矩阵。在模拟过程中充分考虑了气流和温度梯度的影响，模拟结果与实验值吻合良好。开发的软件在消声器CAD方面具有一定的应用前景。更多还原

【Abstract】 Prediction to the performance of exhaust silencers is discussed. Two new sound field transmission matrices for silencing elements is established considering mean gas flow and temperature gradient. Calculating results coincide with testing results. This work will be helpful for further research of silencer CAD更多还原
