摘要

This paper studies numerical methods of sensitivity analysis for coupled structural-acoustic systems with the finite element method. The modal sensitivity analysis method for eigenvalues and eigenvectors, and the MFR sensitivity analysis method for the sound pressure level integral are presented. The numerical examples are presented to illustrate the accuracy of methods. The methods have been implemented with program system JIFEX for the design optimization.
