Abstract：Based on FEM, BEM and PEM, acoustic radiation analysis from random excited structures is investigated in this paper. A new method is presented to calculate random acoustic radiation analysis. 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. Numerical examples show accuracy and efficiency of the presented method.
