Pressure vessel simulation analysis method and model parameter lossless transmission device

Abstract

A pressure vessel simulation analysis method, comprising: collecting objective parameters of existing pressure vessels; establishing a key-value comparison table; using CAD tools to import parameter data associated with structural dimensions to form a wireframe model; using CAE tools to import the wireframe model; The CAE tool forms the wireframe model into a solid model; the CAE tool determines the grid division of the solid model according to the parameter data associated with the structural size in the complete parameter data, and applies loads to the analysis model based on the grid according to the physical attribute parameters in the complete parameter data; The CAE tool optimization result data is output to the key-value comparison table; the key-value comparison table backs up the original parameter value, and updates the original parameter value of the corresponding key-value item. The invention improves the modeling and data operation efficiency of finite element analysis. It also includes a parameter lossless transmission device.

Description

technical field [0001] The invention relates to a data processing method and device, in particular to a data processing method and device for objective model simulation. Background technique [0002] As the thrust system design requires, pressure vessel equipment has been widely used in the development of launchers. The design methods of pressure vessels have been regulated by mature national standards and industry standards, and the strength performance analysis methods mainly include traditional design methods and finite element analysis design methods. The finite element analysis method has the advantages of accurately grasping the dangerous section and reflecting the complex stress field. By establishing a characteristic model for the corresponding pressure vessel, the finite element simulation analysis method for model analysis has been widely used in the industry. [0003] Since the pressure vessel modeling process requires a dedicated CAD modeling tool to complete th...
