對於複材機翼結構,至今已有許多相關文獻探討,其數學模式的建立,包含用實心樑、疊層樑、箱型樑、平板等複材理論來模擬,而本文將以複材夾心疊層板理論為基礎,延續 Moh and Hwu (1997) 之研究,導出具對稱型正交疊層面板之夾心板,一邊為固定端,另三邊為自由端邊界,受x、y方向負載之挫曲強度數值解,並加以考慮翼剖面外型,使用 NACA2412 之翼剖面函數,再使用MATLAB 軟體撰寫成程式,以及有限元素分析軟體 ANSYS 進行挫曲分析,兩者以做驗證與討論。
Several different structural models have been proposed to study composite wing structures such as isotropic beam model,laminated beam model, box model and plate model. By following the study of Moh and Hwu (1997) on composite sandwich plate, in this thesis we use the Rayleigh-Ritz method to attain the buckling load of composite sandwich plates.With the consideration of the airfoil shape, the results were further extended to composite wing structures. Finally a computer program was coded with MATLAB to conduct the buckling analysis,and the results were compared with those obtained by the finite element software ANSYS.
