| Abstract: | The ANSYS finite element method was used to analyze the stress and fatigue of product discharge tank as one of the most important equipments in polyethylene plant. The structure was divided into two parts according to the basic design parameters of the structure. Stress analysis was performed by applying different boundary conditions. The stress assessments of the two structures were carried out by using different paths, and the maximum value of the stress was found. The fatigue calculation on the position with the maximum stress was completed. The results met the strength requirements of national standard JB-4732-1995. |
