Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The invention provides a structural strain energy entropy characterization calculation and result processing system, the basic idea of ​​which is to call the finite element analysis software to calculate through the background, and to extract the results and reproduce the results through the secondary development function of the finite element analysis software Processing (such as text display, 3D point cloud form display, etc.); it is not necessary to open the finite element analysis software on the GUI interface, which saves a large amount of computer resources when the GUI is started. It is faster to call background analysis and result extraction without GUI interface than with GUI interface.

Abstract

The invention provides a structural strain energy entropy representation calculation and result processing system, which can automatically extract various units and node sets in analysis and can enable a user to realize result output and display only by clicking corresponding buttons. According to the system, a finite element analysis model processing module is used for editing finite element analysis model files and automatically storing the edited finite element analysis model files in a working directory of the system; an analysis calculation module is used for performing submitting analysis, stopping analysis and state monitoring on the edited finite element analysis model files to obtain result files, wherein the result files contain all basic data; a result extraction module is usedfor reading all the basic data in the result files and providing the basic data for the user; and a result display module is used for displaying all the basic data extracted by the result extraction module in a text form.

Description

technical field [0001] The invention belongs to the technical field of finite element analysis, and in particular relates to a structural strain energy entropy characterization calculation and result processing system. Background technique [0002] When designing or evaluating a new design structure, it is necessary to conduct finite element analysis on the load bearing of the structure (assembly in most cases) under working conditions. The assembly generally contains multiple contact surfaces, and the stress size and distribution uniformity between the contact surfaces affect the accuracy and stability of the structure. Studies have shown that the larger the entropy value, the better the contact uniformity. Structural strain energy entropy characterization calculation and result processing system is mainly to extract the strain energy density of the structural part concerned after the finite element analysis, and calculate its entropy value based on this; extract the stres...
