| Abstract: | According to strength theory and the stress distribution of edge area of intersecting joints of axial symmetry revolving thin-shell, the equilibrium equations of the joints is established and so is the ultimate internal pressure calculating formulas.The ultimate internal pressure of the tanks is also analyzed through two-dimension elastic-plastic finite element analysis method and elastic analysis theory. The steel tank model is tested under ultimate internal hydraulic pressure. Engineering formulas for ultimate internal pressure of steel chemical tanks are given. |
