摘　　要：给出圆柱薄层壳屈曲的临界载荷,编制了计算程序;探讨了正交铺层的复合材料层合壳在屈曲问题中的某些相似特征,根据模型和原型间在几何上或材料上的相似比,预测出原型的屈曲临界载荷,为复杂结构的参数化设计及研究奠定了基础。This paper gives the buckling critical load of orthogonal laminated cylindrical shell and the computational procedure. Some similar characteristics are discussed in the buckling question of the cross-ply laminated shell. According to the ratio of similitude of the model and prototype in geometry or material, the critical tion for the parametric load of prototype is forecasted in the paper, which has laid down the foundadesign and research of complex structures.

关 键 词：临界载荷 复合材料 相似比
