摘要：Based on FEM, BEM and PEM (pseudo excitation method), acoustic radiation sensitivity analysis and design optimization from random excited structures are investigated in this paper. FEM is used to calculate structural responses, and BEM is used to calculate structural acoustic radiation. PEM combined with FEM and BEM is used to solve the problem on random acoustic radiation. Design optimization model and optimization algorithm flow are presented, and the sensitivity analysis formula are derived on emphasis. Numerical examples show the accuracy of sensitivity and the effectiveness of solved algorithm.
