Research on Process Presentation and Reasoning of Mechanical Motion Scheme Design

摘要

Presentation approaches of mechanical motion scheme must support the whole process of conceptual design. To meet the requirement, semantic network approach is applied to represent design process, actions, mechanisms (P-A-M) and their relationships. Computer aided automatization, which is represented by computer aided motion cycle chart of design scheme, is realized through representation and revision of time coordination and its influence in machine motions, uncertain reasoning technology based on semantic network is applied in mechanism types selection of needle driving mechanism in industrial sewing machine, This modeling method has been effectively proved by the experimental instance.
