| Abstract: | The opening structure with flush nozzle in pressure vessel with ellipsoidal head was discussed with the finite element method（FEM） and the experimental model based on the thin shell theory;and some proposals were proposed for structure design and manufacturing practice;and the method to improve theoretical solution according to welding sizes was proposed.Comparing the analytical results with the experimental data shows that the welding quality at connecting parts can play an important role in structure reinforcement. |
