Simulation Analysis and Database Establishment of Large Spherical Tank Plate Stamping
Based on ABAQUS finite element simulation software,the stamping forming process of 3000m2 large spherical tank plate is studied.Combined with experimental verification,the influencing factors of plate forming quality are analyzed.Based on the setting requirements of stamping pressure parameters,the deformation of plates under different working conditions when stamping with different pressures is studied,and the deformation laws of plates under different working conditions when stamping with different pressures are basically the same,The deformation of the plate increases with the increase of the punching force,and the larger the initial deformation of the plate,the smaller the deformation of the same punching force,and the more difficult the deformation is.Based on the results of simulation process parameters and deformation,the stamping process database of spherical shell plate is established,which is of guiding significance to improve the stamping efficiency of spherical tank plate and optimize the process parameters.
