摘　　要：目前国内外尚未针对专用于醇氢动力汽车的消声器作深入研究。因此论文基于GT-Power对某醇氢动力汽车的排气消声器的消声性能从插入损失、传递损失以及降噪量三方面进行仿真研究。论文的研究对醇氢动力汽车排气消声器的选配和性能优化设计具有重要的工程参考意义。At present,there is no in-depth study on the muffler for alcohol-hydrogen powered vehicles at home and abroad.Therefore,based on GT-Power,this paper simulates the noise attenuation performance of the exhaust muffler of an alcohol-hydrogen powered vehicle from three aspects:insertion loss,transmission loss and noise reduction.The research in this paper has important engineering reference significance for the selection and optimization design of exhaust muffler of alcohol-hydrogen powered vehicle.
