摘　　要：本文利用自行开发的复合材料结构应力分析软件 (CMSSA)对某型导弹的复合材料弹翼——弹身组合结构进行了静力分析。本文的计算软件采用动态链表数据结构存贮总体刚度矩阵 ,具有很高的存贮和计算效率。文中给出了任意四边形壳单元和三角形壳单元的形函数及几何矩阵 ,这两种单元能适应结构中的复杂曲线边界及单元过渡区域。In this paper,the structural static analysis of the combination of the wing and the cabin of a type of air to ground missile was carried out by using the compostie material structural stress analysis software(CMSSA).The solver of this software uses the linked list data structure to store the global stiffness matrix,which is efficient in storage and calculation.The shape function and geometrical matrix of the non orthogonal shell element and triangle shell element are also presented in this paper.These two kinds of elements can fit the complex boundary in structure and the field of element transition
