| Abstract: | The non-linear FEM software LS-DYNA was used to analyze the collision process of different ring-stiffened cylindrical shell under radial impact.Plastic deformation energy,mangled area and impact of ring-stiffened cylindrical shell were discussed respectively under different situation.The results showed that collision performance of three new frame shapes exceed traditional shape,which is helpful to the collision performance optimization of the ring-stiffened cylindrical shell. |
