摘　　要：基于CATIA自定义特征,开发了汽车钣金产品可成形性分析与毛坯展开系统BEW(Blank EstimationWizard),该系统将CAE模型作为CATIA的特征集成于CAD平台上,重点解决BEW系统中CAD设计与CAE分析模型同步更新技术,主要包括产品曲面,以及材料参数、工艺参数、网格剖分、中性层偏置等。开发了汽车覆盖件产品设计同步仿真系统,以避免在平台转化过程中模型数据丢失与精度损失,减少产品设计初期CAE反复建模的时间,提高了设计人员的工作效率。BEW （Blank Estimation Wizard） based on CATIA User-defined Features was developed on the CATIA platform. This system integrated the CAE model into CAD platform as CATIA feature. It focused on solving the synchronization update technology of the CAD design model and CAE analysis model, including product surfaces, material parameters, process parameters, meshing, neutral layer bias. Formability synchronous emulation system for automobile panel design was developed to avoid losing model data and accuracy during the platform transformation. It could save the time of rebuilding CAE model during early stage of product design, and improve the efficiency of the designers.
