摘要

本研究主要探討消音器對於引擎排氣系統的影響，藉此設計出一款搭配於350cc引擎之消音器。此研究目標是使消音器能夠在引擎馬力維持的情況下，噪音降低1~2倍。因此欲進行此研究前，必須先瞭解各項參數對於消音器表現的影響。本研究所使用的分析軟體為Ricardo公司製作之軟體WAVE，透過WaveBulid3D輸入各項參數，並且繪製出消音器模型。再使用WaveBuld將消音器與引擎架構結合後進行模擬分析，針對模擬結果作分析討論與消音器參數之改良。排氣管消音器設計不僅需要滿足聲學性能和氣體動力性能指標，還需要考慮排氣管消音器的結構、材料和安裝空間等方面的要求。

This research investigates the engine exhaust muffler system impact, thereby design a 350cc engine with the muffler of. This research goal is to make the muffler can in the case of engine horsepower to maintain the noise reduced by 1 to 2 times. Therefore, before To perform this research, I must understand the impact of various parameters on the performance of the muffler. Analysis software used in this research for the production of the company's software Ricardo WAVE, enter the parameters through WaveBulid3D, and draw the muffler model. Then use the simulation analysis WaveBuld to combined muffler and engine architecture for simulation analysis, against the simulation results for analysis and discussion of improved parameters of the muffler. Exhaust muffler design not only need to meet the acoustic performance and aerodynamic performance, also need to consider the muffler structures, materials, and installation space requirements.
