探讨可变形机翼中使用双稳态复合材料层合壳结构驱动其变形的潜力。基于最小势能原理,采用有限元法对不同铺层形式、不同材料组分的反对称双稳态复合材料层合壳的力学模型进行了数值模拟和详细讨论,计算确定结构几何尺寸和材料参数对结构卷曲半径的定量影响程度。进而,运用研究得到的层合壳的结构性能,对三种机翼变形方式包括机翼的弯曲变形、平面变化和弦长改变采用双稳态结构驱动进行了分析和讨论,初步探讨其应用于可变形机翼的适用性,并给出一些有益的结果。
To investigate the potential of biaxial composite laminated shell structures to deform in deformable wings. Based on the principle of minimum potential energy, the mechanical model of anti-symmetrical bistable composite laminated shells with different material compositions and different types of cladding layers was numerically simulated and discussed in detail by means of finite element method. The geometrical dimensions and material parameters Quantitative influence of structure radius of curvature. Furthermore, the structural performance of the laminated shells obtained by the research is analyzed and discussed with the bistable structure driven by three kinds of wing deformations, including the bending deformation, the plane change and the chord length variation of the wings, Deformation wing applicability, and gives some beneficial results.
