摘要

研究了面板各向异性和其他物理/几何参数对平面夹层板本征频率特性的影响。该研究是在一个先进的三明治结构模型的背景下进行的。详细分析了与面板几何形状、面板中纤维取向和堆叠顺序以及芯材性能相关的大量参数的影响,并概述了相关结论。在目前的结构模型中获得的频率预测与专业文献中少数可用的频率预测进行了验证,并报告了极好的一致性。

Free Vibration of Sandwich Flat Panels With Laminated Anisotropic Face Sheets
A study of the effect of anisotropy of face-sheets and of other physical/geometrical parameters on eigenfrequency characteristics of flat sandwich panels is presented. The study is carried out in the context of an advanced model of sandwich structures. A detailed analysis of the influence of a large number of parameters associated with the panel geometry, fiber orientation and stacking sequence in the face sheets, and material properties of the core is accomplished, and pertinent conclusions are outlined. Validations of frequency predictions obtained within the present structural model against the few ones available in the specialized literature are accomplished, and excellent agreements are reported.
