| 摘 要： | 制备了多层阻尼复合结构, 应用有限元方法对多层复合结构阻尼性能进行了理论研究。计算结果与实验结果基本一致。利用该有限元模型分析了各层阻尼材料的几何及物理参数对复合结构阻尼性能的影响。分析表明: 阻尼材料的厚度、损耗因子和弹性模量对阻尼复合结构阻尼性能有较大影响, 而阻尼材料的密度对阻尼复合结构阻尼性能的影响不明显。

| Abstract: | The damping composite st ructures with three-layered damping materials were prepared. The dampingproperties were studied with the finite element method. The calculated result s are in good agreement with thosemeasured f rom the authors’test s. Based on the finite element model, the effect s of the geomet rical and physical parameters of damping materials on damping properties of composite st ructures were analyzed. The result s show thedamping material thickness, loss factor and modulus have evident effect s on the damping properties of the dampingcomposite st ructure, but the damping material density has no effect on them. |
