| 摘要: |
| 本文用有限元素法对集中力作用下的薄壁加劲壳进行应力分析，推导了变轴力杆—受剪板模型的元素刚度矩阵，提出了横向构件和边界约束的处理方法。用满应力法对结构进行综合，在调优过程中，受压应力控制的元件采用“同步”迭代格式，并引入了必要的几何约束，优化结果，重量有明显降低。 |

| Abstract: |
| In this paper，the thin wall stiffening shell is analysed by means of the finite element method，the element stiffness matrix of the bar with the variable axial force is derived，and the method dealing with cross-elements and boundary restraint is presented.
The structure is synthesized by means of the full stress method. The pattern of the "synchronized" iteration is used in process of optimization for the elements that are controlled by the pressure stress. At the same time，the necessary geometrical restraint is introduced. The conclusion indicates that the weight for optimized structure is obviously reduced. |
