The finite element analysis and optimized design to large-scale oil storage tank

Large-scale oil storage tank was stored or dressed up crude oil and refined oil .It had been widely applied in the chemical, oil and other industries, but it also was a place where accidents frequently occur. It used the finite element method to analysis and optimized design the large-scale storage tank. It checked stress assessment and intensity calibration of maximum stress concentration. At the same time,the tank and floating roof cylinder wall thickness was optimized. After checking, the large-scale oil storage tank was safe. In the process, manufacturing and conditions permit, we should minimized the cylinder wall thickness of the tanks in order to achieve the optimal design of lightweight structures objectives, but should increased the thickness of floating roof.
