摘要

采用夹芯板进行自由振动分析。采用周期微观结构和Mori- Tanaka模型对单向纤维增强复合材料进行了均匀化研究。在分析和数值分析中考虑了剪切变形理论。采用ANSYS中的有限元法进行数值分析。研究了夹芯板长度、芯层厚度、纤维增强角等设计参数对夹芯板振动响应的影响。夹芯板的固有频率随夹芯板设计参数的变化以图形形式给出。结果表明，夹层板的设计参数对夹层板的固有频率有一定的影响，这种影响对动荷载作用下夹层板的设计具有重要意义。

Dynamic Behavior of Composite Sandwich Panel with CFRP Outer Layers

Sandwich panel with laminate faces is used for free vibration analysis. The periodic microstructure and Mori- Tanaka model are used for homogenization of unidirectional fiber reinforced composite. The Shear Deformation Theory is considered for analytical and numerical analysis. FEM in ANSYS is used for numerical analysis. The effect of sandwich design parameters such as panel length, core thickness and fiber reinforced angle on vibration response is investigated. Natural frequencies of sandwich panel versus sandwich design parameters are presented in graphical form. From the results can be concluded that sandwich design parameters affect the natural frequencies of sandwich panels, and this effect is important for designing of sandwich panels under dynamic load.

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
