| 摘 要： | 应用基于应变能的有限元方法研究了纤维增强复合材料的阻尼特性,此方法从单向复合材料的阻尼性能参数出发,通过有限元模态分析得到复合材料结构的模态损耗因子,与已有的理论分析和试验结果相比吻合较好,从而验证了该方法的合理性。该方法还可以比较三维应力分量对阻尼的贡献。本文将该方法应用于一种复合材料等间距正交网格加筋板的阻尼特性分析,考察了加筋对复合材料层合板阻尼特性的影响。

| Abstract: | The present investigation is concerned with the utilization of the strain energy based finite element method and the damping properties of the unidirectional lamina for predicting the modal loss factor of fiber reinforced composite structure. The results for the vibration and damping analysis of laminated plates obtained by the present method are compared with the results obtained by other authors to verify the reasonability of the present method. Contributions of 3-D stress components to damping can also be studied by this method. The modal loss factor of an orthogrid-stiffened composite panel is studied using the present method and particular attention is paid to the effect of ribs on damping. |
