摘　　要：采用商业有限元软件MSC.Nastran,运用简单的Shell单元对复合材料格栅结构蒙皮和加强筋进行模拟,预测复合材料格栅结构名义纵向拉伸强度/模量,弯曲强度/模量。计算结果表明,随着复合材料格栅中肋高度的增加,名义弯曲强度/模量和拉伸强度/模量均有下降趋势。The mechanical properties of the advanced stiffened grid structure was predicted through MSC. Nastran. The AGS, panel and rib were stimulated through shell cell. Load/displacement curve of the AGS 0° tensile/bend properties show that the AGS have the excellent mechanical properties. The AGS 0° tensile/bend properties decrease with the height of the AGS increasing for the rib contributing factor increasing in the total AGS mechanical properties.
