| 摘 要： | 建立消声器的ANSYS仿真模型,分析原消声器的消声性能,通过建立三维仿真模型,研究两腔串联的复杂式结构消声器的消声性能,结果表明,改进后增加了消声器低频带的宽度和中频范围内的消声量,同时稳定高频振荡,但在1 550 Hz和2 300 Hz仍存在问题,加入端部共振腔后,低频段的消声量明显增加,2 300 Hz高频带得到改善.

| Abstract: | A finite element model of the muffler by using software ANSYS is established to analyze acoustic attenuation performance of primary muffler. By establishing 3D ANSYS simulation model, double chamber series construction muffler is researched. And analysis shows that low-band width and noise attenuation of frequency-band are increased, while frequency vibration is more steady. But problems are still not solved ranging from 1 550 Hz to 2 300 Hz. A resonator is added to the muffler, and analysis shows that noise attenuation in low-band increases obviously, and the high-band in 2 300 Hz is improved. |
