摘要: 本文针对复合材料层合板阻尼性能参数进行敏感性分析,采用悬臂梁振动试验测试与应变能有限元仿真相互验证,试验结果表明纤维种类、纤维体积含量、纤维角度和加载频率均是影响复合材料阻尼性能的重要参数,其中纤维角度和加载频率影响程度明显,同时本文采用的应变能有限元法与实验结果拟合较好,可以用于预测复合材料层合板不同纤维角度下的阻尼损耗因子。

Abstract: This article aims at the sensitivity analyzing of the performance parameter of composite laminate combined with cantilever beam vibration test and strain energy finite element simulation to cross authenticate. The test result shows that the fiber type, fiber volume content, fiber angle and loading frequency are all important parameters which influence the damping performance of composites. Fiber angle and loading frequency show significant influence on composites. Meanwhile, the strain energy finite element method this article used is fitting well with the test result and can be used to estimate the damping factor of composite laminate under different fiber angles.

Key words: composites material, damping, sensitive parameter, finite element
