Research on calculation methods of cylindrical shell Deformation |
|
| Abstract: | Calculation on the deformation of cylindrical shell is a key problem, analytical method, numerical method and semi-analytic method become effective method to solve these problems. Because of the complexity of ring-stiffened cylindrical shell,it is difficult to use analytical method, FEM becomes the representation of numerical method by the developing of computer technology. The stress condition of typical cylindrical shell was anslysed in this paper, and the FEM model was established. According to the contrast of analytical method and numerical method, The influence of different methods to the cylindrical shell deformation was analysed. |
