Pressure vessel simulation analysis method and lossless model parameter transmission device

Abstract

The invention relates to a pressure vessel simulation analysis method. The pressure vessel simulation analysis method comprises the steps of acquiring objective parameters of existing pressure vessels; establishing a key value comparison table; using a CAD (Computer Aided Design) tool to import parameter data correlated with structural dimension to form a wire-frame model; using a CAE (Computer Aided Engineering) tool to import the wire-frame model; enabling the wire-frame model to form a solid model through the CAE tool; determining the meshing of the solid model by using the CAE tool according to the parameter data correlated with the structural dimension in the complete parameter data, and applying load to an analysis model based on meshes according to physical attribute parameters in the complete parameter data; using the CAE tool to optimize result data and outputting the result data to the key value comparison table; backing-up the original parameter values through the key value comparison table and updating the original parameter values of corresponding key value items. By adopting the pressure vessel simulation analysis method, the modeling and data operation efficiency of finite element analysis is improved. The invention additionally provides a lossless parameter transmission device.
