Virtual manufacturing system for autopanel stamping based on Internet/Intranet

提出基于 Internet/ Intranet汽车覆盖件冲压虚拟制造系统。在基于 Internet/ Intranet的信息系统集成的基础上 ,利用虚拟现实、科学可视化和多媒体的虚拟使用环境 ,在人工智能技术和基于事例的推理 (CBR)技术的支持下 ,通过集成地应用各种建模、仿真分析技术和工具以及控制技术实现集成的、并行的产品开发和制造系统 ,采用在虚拟环境下的基于黑板控制系统的分布式并行处理协同求解。最后给出了汽车覆盖件典型的拉深工艺的界面交互计算实例。

In this paper ,A Virtual Manufacturing System (VMS)for Autopanel Stamping Based on Internet/Intranet is proposed.The Internet/Intranet based information system is used to act as the platform of VMS,and some popular computer techniques such as Virtual Reality,Multimedia and Scientific Visualization are applied to construct the virtual environment of VMS.Depending on the Expert Systems and Case based reasoning(CBR),the chains of modeling ,simulating and controlling are integrated to realize the VMS for Autopanel Stamping .The authors also shows the cocurrent processing approach based on the Blackboard Control System on virtual environment,and the user interface of the VMS is illustrated by the example of deep drawing of Autopanel.
