摘　　要：以某摩托车排气消声器为研究对象,运用有限元前处理软件Hypermesh建立消声器声场模型,根据声学有限元法分析消声器的声学性能并计算其传递损失,分析结果清楚地反映了摩托车消声器内部声场的情况,为该消声器的改进设计和优化设计提供依据。This research takes a motorcycle exhaust silencer as a study object, and a muffler sound field model is established by using the finite element pre-processing software Hypermesh. According to the finite element analysis of acoustics, silencer acoustic performances are analyzed and the muffler transmission loss is calculated. The results clearly reflect the motorcycle muffler sound field conditions, and provide a basis for the muffler＇ s improving and optimal design.
