摘　　要：采用板壳大变形的Ｋｉｒｃｈｈｏｆ－Ｌｏｖｅ假定和扁壳近似及复合材料的有关特性，推出在静水压力（或侧向压力）作用下的两端简支准对称缠绕有限长圆柱壳的Ｋａｒｍａｎ－Ｄｏｎｎｅｌ方程，求出相应的特征值及原始分叉点．General equations(Karman Donnell equations) for a simply supported,finite length and approximate symmetric rewound cylindrical shell subjected to hydrostatic or lateral pressure are derived,by using the related characteristic of composite material,the Kirchhoff Love’s hypotheses of moderately large deformation of shell as well as shallow shell approximation.The eigenvalues and multiple eigenvalues are obtained and the primary bifurcation points are gained.

关 键 词：复合材料 圆柱壳 分叉
