Abstract: To improve the efficiency and accuracy of design knowledge acquisition,an active knowledge push service technology based on design intent modeling was proposed.The formalized design intent model that involved target function,constraints and user interests was established for design tasks,and the standardized organization of various design knowledge in mechanical conceptual design phase was managed.Based on design intent model and design knowledge base,the knowledge push mechanism and the solving method for knowledge matching with Function-Behavior-Structure(FBS)mapping were given.A prototype system of knowledge service system for mechanical conceptual design was developed,and a case of piston pump design was used to demonstrate the availability of the system.

Key words: conceptual design, design intent modeling, knowledge organization, knowledge push, function-behavior-structure mapping, product design
