【Abstract】 This paper presented the stress analysis and the design for the 1000m3 spherical tank. The stresses in the shell of tank and in the structures of openings at the top and bottom crown of tank under the several conditions including pressure-testing, operating, seismic and pressure circle fatigue were analyzed by means of the finite element analysis. The stress strength and fatigue life of the tank were evaluated and checked.更多还原
