基于不相干平面波叠加以模拟混响声场的航天器低频声固耦合分析
Low-frequency acoustic-structure coupling analysis of spacecraft based on acoustic diffusion field modeled with combined uncorrelated plane waves
摘要
Abstract
The vibro-acoustic analysis is one of the important parts in the spacecraft design. This paper proposes a method to model the acoustic diffusion field by combining uncorrelated plane waves linearly and its justification is shown theoretically. The parameters for each plane wave are also obtained in the paper. After that, a satellite vibro-acoustic problem is simulated using the FEM-BEM method and the results are validated by the test data, which shows that the method is theoretically correct and could be used to analyze the vibro-acoustic response of spacecraft.关键词
