| 摘 要： | 为了解决虚拟装配系统中装配意图的捕获、零件模型的精确定位等问题，提出一种框架数据模型。将典型装配过程性知识封装到过程框架中，将蕴藏在零件模型B-rep中的工程信息封装到特征框架中，框架实例对象同产品层、显示层中的数据对象一起构成框架数据模型。应用结果表明，数据模型不仅满足了装配信息完整性和虚拟现实实时性的要求，而且帮助解决了上述问题。 |

| Abstract: | For purpose of resolving problems such as locating part model precisely,perceiving User's assembly intention in a virtual environment,a data model was proposed based on frame theory.The process frame encapsulated knowledge about typical assembly processes.B-rep information was transformed to feature frame which described part structure from assembly view.The data model was composed of frame objects and objects in product and display layers.Application results show this data model not only meets the requirem... |
