摘要

本文对不同边界条件下蜂窝夹层结构的自由振动、模态和应力状态进行了分析，确定了材料或参数变化对夹层频率和刚度的主要影响因素。通过与文献结果的比较，对本文所采用的代表性体积元(RVE)方法进行了分析和数值验证。首先，采用单元胞法在ANSYS中捕捉不同参数对蜂窝夹层结构自由振动的整体影响;对不同芯材组合的蜂窝夹层结构进行了固有频率分析。考虑并考察了箔片厚度、边界条件、材料选择、密度和裂纹存在对夹层结构的影响。提出的核心有一个内置的不同材料的形状钢筋有效的共振，疲劳和变形抗力在更高的频率。

FREE VIBRATION INVESTIGATION ON RVE OF PROPOSED HONEYCOMB SANDWICH BEAM AND MATERIAL SELECTION OPTIMIZATION

In this paper, free vibration, modal and stress state analyses of honeycomb sandwich structures with different boundary conditions was investigated and major factors affecting the sandwich frequencies and stiffness due to material or parameter changes were determined. The representative volume element (RVE) method used in this work were analytically and numerically validated by comparing the obtained results to those available in literature. Firstly, unit cell method was used to capture the entire effects of different parameters on the free vibration of honeycomb sandwich structure in ANSYS. This study analyzed the natural frequencies of honeycomb sandwich structures with different core materials combination. The effects of foil thickness, boundary conditions, materials selection, density and presence of crack on sandwich structure were taken into consideration and examined. The proposed core had an inbuilt shaped reinforcement with different materials for effective resonance, fatigue and deformation resistance at much higher frequency.
