| 摘 要： | 针对由约束阻尼结构和离散型阻尼器组成的复合阻尼结构,建立了有限元仿真模型,利用大型有限元程序NASTRAN对其进行了复特征值分析.与实验结果比较表明,所建立的有限元模型能较好地分析计算结构在不同方向上的减振特性.基于提出的有限元仿真模型,分别对复合阻尼结构的约束阻尼结构和离散型阻尼器进行了优化分析,得到具有更佳减振效果的复合阻尼结构.

| Abstract: | A finite element model for complex damping structure comprised of constrained damping structure and discrete damper is presented and computed by complex eigenvalue analysis in NASTRAN software.Comparisons are made between results obtained by software simulation and by experiments.It is shown that the reducing properties of the vibration at different directions of the complex damping structure are able to be well analyzed by the finite element model.On the basis of the proposed finite element model,a complex damping structure with better function of vibration reduction is derived from the respective optimal analyses to constrained damping structure and discrete damper. |
