Connection Knowledge System for the Assembly Sequence Planning

The design process of product is a process that uses engineering connection knowledge to assemble each functional unit, and the essence of which is the application of assembly connection knowledge. In the development of assembly design system which based on the knowledge of engineering connection, the assembly sequence planning is considered, and a new method of design and application of knowledge system is put forward. Firstly, the basic engineering connection relationship is analyzed, and the Problem Oriented Analysis and Decision Expert System (POADES) method is used to construct the knowledge mainframe tree, and then the basic connection classes (namely the connection nodes) are determined to realize the mapping relationship between the assembly model and the mainframe tree of connection knowledge. Finally, in order to provide convenience for the assembly sequence planning, the map data and the assembly sequence planning data are attached to the nodes.
