摘要

摘要: 通过gt-power软件对发动机某一转速下排气系统尾管噪声进行仿真。提出几种消声器改进方案，选出最佳方案。在该方案基础上，分析几种因素变化对消声器性能影响，选出较为理想的参数。最终使功率损失、插入损失等指标达到较好的水平，解决了尾管噪声过高的问题。得出了穿孔管，插入管长度，扩张腔体积对消声性能影响较大的结论。

Abstract: The tailpipe noise of some automotive exhaust system was simulated in some speed of engine with gt-power software. Several improved schemes of exhaust system muffler were put forward, and then choose the best one from them. Based on the best scheme, the impact of a few factors changes on noise elimination was analyzed, and ideal parameter scheme was selected. Finally, main indexes such as power loss and insertion loss all reach a preferable level; the tailpipe noise is decreased greatly. It is concluded that the lengths of perforated pipe and insert pipe, and the volume of expansion chamber have a great impact on noise elimination.
