This study used computer aided design software Solid Work to draw four models of pressure vessel, and to analyze the displacement and the stress by the finite element analysis software ANSYS.
To carry on the main body of the pressure vessel and find the highest stress of the pressure vessels by finite element analysis. The stress analysis of the pressure vessel main body contains main nozzle, the skirt of the main body ban and the connected control line. And the stress analysis factor includes: the stress distribution situation by seismic force and the displacement change factor of the wind power and the stress distribution condition of the thermal load by expand with heat and contract with cold (normal temperature climb to high temperature). The researcher also discussed the difference of the stress distribution between individual analysis and the overall analysis. The present study used finite element analysis (contain main body, spray nozzle, skirt in view of the overall analysis ban) to carry on the shell individual analysis first, then using the boundary condition of the result displacements regarding connected spray nozzle, the pipeline by the shell analysis again carries on stress analysis of the spray nozzle and the pipeline. Based on the results of stress analysis by the finite element method, the researcher discussed the differences of stresses between overall analysis and the individual analysis results.
