| Abstract: | The numerical simulation and sensitivity analysis of coupled acoustics-structure system are studied by the finite element method in this paper. By the research of numerical method in the structure design stage, the sensitivity of eigen frequency and eigen vector are sdudied based on size design variable. The correctness are showed by the exalmple. The method can provide the theory and algorithm basis of the coupled system design. |
