Abstract

The invention discloses an automatic data conversion method between a three-dimensional modeling software and a finite element analysis software, which comprises the following steps of starting the finite element analysis software, loading the model and performing finite element analysis; starting the three-dimensional modeling software in the finite element analysis software; reading files and performing finite element analysis in the finite element analysis software; saving the result in format of data file by utilizing a data post-processing module and the read and write function of the finite element analysis software; and circularly running the above processes by utilizing the process control command of the finite element analysis software. The automatic data conversion method achieves seamless integration of the powerful modeling function of the three-dimensional modeling software and the finite element function of the finite element analysis software and provides a scientific, high-efficiency and reliable solution for design and analysis of a complicated mechanical system, thereby increasing the product design accuracy and design efficiency.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a method for automatic data conversion between three-dimensional modeling software and finite element analysis software. Background technique [0002] At present, there are many CAD / CAE digital engineering design software, each of which is suitable for different professional technical fields, even if they belong to the same field, they have their own characteristics and advantages. The 3D modeling function of the 3D modeling software is powerful, and it is convenient to modify the model size and structure, but the finite element analysis function is weak; while the finite element analysis software has powerful finite element functions, which can analyze and solve the mechanical properties of the model such as stress and strain, while the 3D Modeling capabilities are weak, often requiring other CAD systems to create models. Making full use of all kinds of powerful engineering des...
