摘要
采用结构辐射噪声FEM/BEM预测模型,对复杂结构进行了模态分析和噪声预测,研究了两种不同约束条件下薄壁构件的辐射噪声。结果表明,不同的约束条件下,复杂结构辐射噪声的主要来源不同。
Using noise prediction model with FEM/BEM,the modal analysis and prediction of radiated noise of a complex structure were done. Then radiated noise of a thin structure under two different constraint conditions was predicted. The result indicates that the noise resources of a complex structure are different with different constraint conditions.
