Abstract

Abstract:

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. 

Key words:

SolidWorks, further development, sheet metal forming, inverse approach of FEM

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。
