基于COM/DCOM的分布式零件参数化 设计系统的研究

为解决基于UG(Unigraphics)的零件分布式设计的问题,分析比较了UG二次开发的两种模式,提出了一种基于零件库的通用参数化设计方法.采用COM(Component Object Model)方式建立了一个基于UG外部开发的通用参数化设计组件,利用DCOM(Distributed Component Object Model)实现了该组件的网络化,并在此基础上选用分布式三层网络模型,构建了一个基于COM/DCOM的分布式零件参数化设计系统,实现了LAN(Local Area Network)下对零件进行参数化设计的功能.

Distributed part parametric design system based on COM/DCOM

To implement the distributed part design based on UG(Unigraphics), two application development modes of UG were compared, and a universal parametric design method on the basis of a part library was presented. Through UG external programming, and utilizing COM (component object model), a universal software component for part parametric design was written, and then with the help of DCOM (distributed component object model), the distributed design using this component was achieved. Finally, considering the 3-tier network model, a distributed part parametric design system integrating this component was developed, which implemented the parametric design in a LAN (local area network) environment.
