摘要
Numerical methods for predicting the behavior of structural acoustic systems are becoming increasingly practical. In this paper, the theoretical basis of the most popular state-of-the-art numerical structural-acoustic analysis techniques, the finite element methods and boundary element methods, are described in general terms. Typical approximations are described to identify both the best utilization and the limitations of the methods. Models for cases of heavy and light fluid loading are discussed. The methods are compared to each other and to analytical methods. A comprehensive literature review is included for identification of more complete references describing the methods.
