Tian S., 2016, Mechanical Product Collaborative Design and Examples Expression Based on the Hierarchy Design, Chemical Engineering Transactions, 51, 1321-1326.
Based on the mechanical characteristics of product information from life cycle, we analysis the hierarchy structure of the three-dimensional the decomposition product composition information. Information describing the object, and then build three-dimensional mechanical product lifecycle unified information model. While the full expression of the product life cycle of information, there is no redundancy and cross information while a hierarchy of information makes analysis of information more convenient and effective. The establishment of a central view of product lifecycle information models body. According to the three dimensions of products were selected to describe the typical information object establish the appropriate ontology model. To achieve a comprehensive information and mechanical products to describe the relationship, particularly the expression of fine granularity mechanical products to the functional surface for subsequent knowledge discovery and reuse of the foundation.
