| 中文摘要: |
| 应用有限元法 ,建立了变厚度薄板三角形单元刚度矩阵 ,给出了变厚度薄板三角形单元形心上的应力和位移计算的数学模型。通过对某型反坦克导弹弹翼进行静力分析和实验比较 ,表明采用这种模型进行分析合乎结构设计精度要求 |
| 英文摘要: |
| By using the Finite Element Method, a stiffness matrix of triangular unit of the light gauge sheet with variable thickness is deduced and a mathematical model for calculating the stresses and displacements at the center of the triangular unit is established. Comparing the static force analysis results of a missile wing with the experimental results show that the proposed model can meets the requirement for the structural design accuracy. |
