针对由优化设计方法、有限元动力计算、灵敏度分析与结构动力修改而制造的圆盘式消声器，运用实验模态分析技术，寻找哪些振动模态与噪声信号有关，更好地了解消声器的动态特性。它为获得优良的消声器提供有效的手段。
In view of the disc muffler manufactured by the optimized design method, the finite element dynamic calculation, the sensitivity analysis and the structural dynamic modification, the experimental modal analysis technique is used to find out which vibration modes are related to the noise signal to better understand the dynamic characteristics of the muffler . It provides an effective means of obtaining an excellent muffler.
