摘    要:采用CAA二次开发技术,设计开发了基于CATIA平台的汽车覆盖件产品设计可成形性仿真系统BEW(blank estimation wizard)。该系统利用CATIA发布(publication)功能,实现CAD与CAE模型的同步更新,减少产品设计初期CAE反复建模时间,避免模型数据丢失和精度损失。系统基于改进的有限元逆算法,根据零件形状或带有工艺补充面的工件形状,即可快速计算出冲压件的毛坯形状,预测零件的应力应变分布。作为DFM的有效载体,系统可应用于汽车覆盖件产品设计初期,帮助企业提高新产品工艺质量和产品质量,缩短新产品开发时间。

关 键 词:CATIACAA  汽车覆盖件  可成形性同步仿真  DFM  有限元逆算法

Abstract:The CAA further development technology has been applied to design and develop the formability synchronous emulation system BEW(blank estimation wizard) for automobile panel product design based on CATIA.Employing the publication function of CATIA,this system can update CAD models and CAE models synchronously,which can save the CAE modeling time repeatedly during early stage of product design,and avoid losing model data and accuracy.Based on improved inverse approach of FE,the system can calculate the blank shape of stamping parts and forecast the distribution of stress and strain on the parts according to the part shapes or workpiece shapes with binder surface.As an effective carrier of DFM(design for manufacture),the system can be applied to the early stage of automobile panel product design,help the enterprise to increase the process quality and product quality of new products,and shorten develop time of new products.
Keywords:CATIA CAA  automobile panel  formability synchronous emulation  DFM  inverse approach of FE
