| 摘 要： | 为了分析剪切变形对夹芯复合材料悬臂箱梁挠度的影响,推导了夹芯复合材料薄壁箱梁的等效弯曲刚度和剪切刚度,将夹芯复合材料悬臂箱梁等效为具有等跨度等刚度的均质箱梁;利用初等梁理论得到了考虑剪切变形的夹芯复合材料悬臂箱梁的挠曲线方程;分析了剪切变形对夹芯复合材料薄壁箱梁挠度的影响,为复合材料薄壁箱梁的设计提供了理论参考.

| Abstract: | To analyze the flexibility effect of shearing deformation on cantilever box girder of sandwich composite materials,the equivalent bending stiffness and shear stiffness of the box girder are deduced,the cantilever box girder is equivalent to an isotropy box girder which has the same longspan and stiffness.The flexibility which takes shear deformation into account of sandwich composite materials of cantilever box girder is analyzed by primary beam theory.The effect of shear deformation to the whole flexibilit... |
