Simulation Optimization Design of Pressure Vessel Pressure-Bearing Cover Plate
Firstly,the maximum stress value at the perimeter and the maximum deflection at the center of the pressure-bearing cover plate are obtained through theoretical calculation.Secondly,the finite element software ANSYS/Workbench is used to simulate and analyze the pressurized cover plate to calculate the maximum stress at the periphery and the maximum deflection at the center of the actual model,and then optimize the structural dimensions of the pressurized cover plate to reduce the maximum stress inside the pressurized cover plate to meet the usage requirements.On this basis,the finite element mesh is further refined,and the maximum stress and maximum deflection in the center of the pressurized cover plate tend to be stable after refinement.Comparing the theoretical calculation results with the finite element simulation results,the simulation results are closer to the actual real value,which indicates the accuracy of the simulation results,and provides a theoretical basis for the actual engineering design process of pressure vessel type pressure cover.
