摘要
本文利用GT-Power软件对某款汽车排气消声器进行了数值分析,并提出了改进方法。仿真结果表明,改进后消声器的消声性能有一定的改善,较好地满足了消声器的消声性能指标。并通过实验测量验证了仿真分析结果,两者结果体现了较好的一致性,并得出一些有益的结论。
In this paper,the numerical analysis on GT-Power is applied to analyze an improved exhaust muffler.The simulation results show that the exhaust muffler＇s performance is improved obviously,which satisfied exhaust muffler＇s noise elimination performance.The analysis result is verified by the test,and two results are consistent with each other.Finally,some beneficial conclusions are drawn.
