| Abstract: | In this paper, the effect of disc muffler on vibration and sound radiation of worm shell is discussed. On the basis of finite element modal analysis and experiment modal analysis, parameters identification is done and the inherent frequencies and modal shapes are obtained. The veracity and reliability of finite element model are validated through contrasting results of finite element modal analysis and experiment modal analysis, it lays the theory foundation to the damp disgasal of shell. |
