The Mainframe, knowledge base and reasonillg machine of expert system for dimension synthesis of
planar linkage mechanism(ESDSPLM), dimension synthesis methods and simulation of design result are
studied in this dissertation.
Through the study of expert system construction theory and technology, mainframe of the ESDSPLM
is built. By using of the dialog box nesting technology, the design wizard is created, which can guide user
to colmplete thc data input step by step. The usage of the design wizard make the ESDSPLM possess of
friendly interface.
Based on the model of Microsoft Data Access Object(DAO) and the technology of Object-Orient
database, the knowledge base of the ESDSPLM is constructed. The Manage system of knowledge base is
built, which call maintain rule in the knowledge base. Though studying dimension synthesis methods
systematically, mnore than forty rules are concluded, which are the base of reasonable dimension synthesis.
The method base class is established, which gathers a lot of synthesis methods,include analytic
method, optimum method, characteristic parameters method, etc. The six-link, four-link and slide-crank
mechanisms for function, path and motion generation can been synthesized by use of these methods. The
numerical atlas of four-link is cleated, which include more than 3,0000 records. At same time Ule atlas
management systenl is created.
The post processing module is the import part of the ESDSPLM, by which user can obtain and
simulate design result. At last the performance parameters are displayed in the mainframe.
By integrating relative function, a platform for dimension synthesis is offered. Friendly interface,
easily operation, high automatic level and elementary reasoning ability are the characters of the
ESDSPLM. So, the expert system occtupy a high value of application.
With the tool of Visual C++6.0, the ESDSPLM is achieved through programming on the Windows 98
platform. Many kinds of dilnension synthesis examples are given in order to explain the use of the
ESDSPLM.
