The Development Of Mechanical Transmission Design Expert System

With, the widespread application of computer technology, the CAD technology for mechanical products also obtains the rapid development, But when involving to make scheme choice, appraisal, analysis and important parameter choice and so on, the CAD technology often needs human's help. Thus, the quality of the person who designs the product still play a important role in the design result. Therefore, how to use the capability of CAD system to design and draw quickly, and at the same time make the design of the product get the expert level, is the goal which the machinery engineering is pursuing unceasingly.For achieving this goal in the mechanical drive design, we has developed Mechanical Transmission Design Expert System (for shot: MTDES) using Visual Basic, Access and Auto CAD. MTDES consists of two parts: Transmission Scheme Design (for shot: TSD)and Part Design (for shot: PD) .The principles of construction of the two parts are introduced, and the design of knowledge-database and the control of ratiocination are described in details. MTES can achieve the total design process which is from the design of transmission scheme, part design to generation of the part drawing. Moreover, MTDES can calculate precisely and design superior, Therefore, it conforms to design person in various levels specification.
