A symbol model of the function decomposition of a design object is built, the structure is solved according to the function-structure mapping, the symbol model of structure scheme meeting the function meeting the function requirements is formed, and a concept design process based on symbol model is presented.
Multi-body simulation modeling is very important in simulation and optimization of products. Considering the problem of rapid modeling in multi-body simulation, the method of dynamic modeling based on inheriting and transforming is presented. For inheriting the dynamic constraint information of the multi-body simulation model, topological configuration of the multi-body simulation model is built,...
The conceptions of basic product unit, product block and primitive mapping are presented, and the composing and assembly relationships between basic product unit and product block are introduced. Combined with primitive mapping, driven approach for knowledge-based product design is proposed. Under the guidance of knowledge, design information is automatically transferred from the conceptual design...
