Optimization of CAD information integration system using computer network design

Abstract

In this paper, the definition of the finite element model is added to the geometric model based on B-Rep structural representation as an analytical feature, and a parametric CAD network-integrated model containing geometric modeling data and finite element feature attribute data is proposed. And the automatic extraction of the finite element model and the dynamic linkage with the integrated model is realized on the professional CAD platform by using parametric hybrid modeling, automatic finite element meshing, and engineering attribute assignment techniques. On this basis, a framework of CAD information integration and optimization design system integrating design, analysis, evaluation, and optimization functions is constructed. In this paper, a prototype system of optimization design based on a CAD network-integrated model is developed, and the system functions are introduced through application examples to prove the effectiveness and feasibility of the system. The research seamlessly integrates CAD integrated design technology, numerical simulation technology, comprehensive evaluation technology, and optimization design technology with professional CAD platforms, reduces the conversion of models in the design and analysis process, reduces the dependence of design solution evaluation on the experience of technicians, and is of great significance in promoting the automation and intelligence of CAD information integration system.
