摘要
根据由最优化方法设计得到的圆盘式消声器，并对该消声器进行了有限元动力计算，在初步了解消声器的动态特性的基础上，对消声器进行灵敏度分析与结构动力修改，使消声器获得优良的动态特性，脱离易发生共振的频率区域，降低噪声辐射，使消声器动态特性稳定，延长使用寿命。
This paper carries out the sensitivity analysis and structure dynamic modification according to the disc muffler obtained by using the optimum design way of finite element calculation and preliminary learning of dynamic behavior of the muffle so that the mufler will get a good dynamic belavior in order to separate it away from the area resonance easily and to reduce noise radiation, to keep the dynamic behavior steady and to prolong its life
