A Kind of CAD/CAE Integrated Modeling Technology Based on FEATURE

Abstract

A kind of CAD/CAE integrated modeling method based on feature is proposed. Firstly, analysis features are attached to CAD model of part and standard part library is formed. Secondly, the CAD model is created using standard parts. Thirdly, geometry information of analysis features is extracted from CAD model and is reconstructed automatically under CAE environment. Finally, based on feature-based meshing and combination technique, CAE model is built quickly. A prototype software for large-scale antenna structure (LSAS) CAD/CAE integrated modeling has been developed and used in performance analysis of a 16-meter-diameter LSAS. The method has been proved to be useful for improving speed, accuracy and consistency of complicated structure CAE modeling notably.

“…These advantages bring significant financial benefits to companies. Typically, there are several main waste sources in manufacturing processes: transport, inventory, motion, waiting time, over production, over processing, defects, and ineffective production that do not meet customer requirements [57]. To eliminate the waste among these eight sources and create value, lean manufacturing uses tools and techniques such as:…”

“…Early research mainly focused on the idealization of CAD models and automatic mesh generation. A workflow of the CAD/CAE integrated modeling method has been suggested by Li et al [57], as shown in Fig. 8.…”

“…Since 1990s, a feature-centric CAD/CAE integration approach has been developed by a number of researchers [56,57,82,110]. In an early effort [82], a part library with built-in analysis features was first established by an expert CAE engineer.…”

“…First, the method abandons an oft-required feature reformation process (from CAD to CAE) that is still technologically immature, and instead binds the analysis features within the parameterized CAD model [82,110]. More progress has been made to improve the reliability of obtaining the analysis feature from the CAD model [57]. Second, automatic mesh generation based on analysis features is a straightforward technique.…”
