摘要
本文探讨了声波在消声管道中的传播特性,建立了内燃机排气消声器常用消声元件的声场传递矩阵,并通过几种消声器在两种内燃机上的插入损失试验结果,验证了理论计算的正确性。
Sound transmission performance in silencing pipes was discussed and sound field transmission matrixes for silencing elements usually used in mufflers was established. Theoretical calculation was validated by the experiments on insertion loss for several mufflers in two kinds of engines.
