| Summary: | 碩士 === 國立臺灣大學 === 機械工程學系 === 86 === This thesis uses the concepts of Object-Oriented Methodology to
develop an expert system shell for assembly design of mechanical
systems. First, an object-oriented knowledge representation method
is defined for representing the necessary design data and design
parameters for a mechanical assembly, then the connective
relationships between mechanical components are established by the
concepts of semantic network. A constraint representation format
is developed to represent the design constraints between components
of the system. Finally, an expert system shell is developed for
operation and management of the knowledge base. After the initial
data for the system are specified, assembly parameters for all
feasible solutions can be found through the inference engine by
satisfying the design constraint. The solid model of the assembly
design for any feasible solution can be automatically generated in
AutoCAD software. The detail design process of some demonstrative
examples are included to show the capability of the developed expert
system shell. The design process of two real machines are also
included. It shows that the developed expert system shell can handle
the assembly design easily and effectively.
