中文摘要：

在SolidWorks平台上,开发了一套面向冲压工艺的坯料展开模拟系统SW-BEX,该系统基于有限元逆算法,具有完整的前后处理功能。阐述了SW-BEX的设计和开发流程,详细研究了在SolidWorks环境中进行网格剖分、约束定义等系统实现的关键技术。以典型的钣金件为例,应用SW-BEX进行展开分析,说明了系统具有易操作性和实用性。模拟结果与实验结果的比较,验证了系统具有很高的模拟精度。SW-BEX完全集成于SolidWorks环境中,避免了传统CAD和CAE软件间模型转换带来的数据损失,实现了真正意义上的CAD/CAE的无缝集成。

英文摘要：

A process-oriented sheet metal unforming simulation system SW-BEX（stamping works-blank estimation xpert） with pre-process and post-process was developed,which was integrated into SolidWorks software and based on the inverse approach of FEM.The design process and development process of SW-BEX was introduced,and some key techniques of the system development were studied,such as meshing and constraint definition.By analyzing a typical sheet metal using SW-BEX,the easy operating,practicality of this system are demonstrated,and the simulation accuracy of this system was verified by comparing the simulation results with the experimental ones.SW-BEX is fully integrated into the SolidWorks platform,avoids the problem of accuracy loss caused by model data exchange between CAD platforms and traditional CAE software,and achieves the real CAD/CAE seamless integration.
