A system for supporting rapid assembly modeling of mechanical products via components with typical assembly features

摘要

During assembly modeling, standard parts and some existing components with a typical assembly feature (TAF) are often directly inserted into the assembly model of a product and the design time could be reduced if these components are managed effectively. In this paper, the concept of the TAF is given from the function view. To reduce the complexity of the assembly modeling process, the types of constraints are summarized through an assembly process research and a parameterization method on component level is introduced. After that, a convenient and powerful assembly mechanism for components is proposed on the basis of the features and the constraints among them. Furthermore, a component database and a system for supporting rapid assembly modeling are developed based on a flexible coding system and a method to retrieve the components is given.
