Through making use of the finite element method,the stress distribution law at the pressure vessel' s opening-nozzle zone was studied and the stress intensity of the dangerous areas were evaluated to show that, the stress distributions over cylinder and nozzle areas is complex along with a obviously-changed gradient;and the maximum stress can be seen at the inner side of the cylinder body-nozzle junction and it's distributed sym-metrically and it's also the most dangerous area of cylinder failure.Under the condition of ensuring safe oper-ation of the pressure vessel,the structure of vessel is optimized and the optimal solution to the container design is calculated and analyzed to achieve efficient and safe operation of the container and the reduction of the man-ufacturing cost.
