摘　　要：文中测量了类似均布载荷下夹芯复合材料加筋板的变形值,使用实体单元建模方法和实体单元、壳单元相结合的简化建模方法建立了6个不同网格尺寸的有限元模型.有限元计算结果表明:使用实体单元、壳单元相结合的简化模型4可以以较高的计算效率取得误差在5%以内的计算结果.有限元建模此类夹芯复合材料加筋板时可使用实体单元、壳单元相结合的方式来简化,且复合材料蒙皮的网格尺寸应控制在蒙皮厚度的10倍左右,夹芯厚度方向至少划分两个网格.The deformation values of sandwich composite stiffened plates under similar uniform load were measured,and six finite element models with different mesh sizes were established by using solid element modeling method and simplified modeling method combining solid element and shell element.The results of finite element calculation show that the simplified model 4,which combines solid element and shell element,can obtain the calculation results with higher calculation efficiency and the error is less than 5%.The finite element modeling of this kind of sandwich composite stiffened plate can be simplified by combining solid element and shell element,and the mesh size of composite skin should be controlled at about 10 times of skin thickness,and the number of mesh in the direction of sandwich thickness should be divided into at least two.
