In order to reveal the stress distribution rule of large opening fatigue pressure vessel, the 3D finite element model is established. The stress distribution results are obtained after the load with bearded boundary conditions in the model. Linearity stress intensity evaluation and fatigue analysis results are achieved according to JB 4732—1995. The reference signiifcance and theory basis for design and optimization of fatigue pressure vessel are provided by the analysis process and evaluation results.
