Expert System for Designing Shaft-Bearing-Gear Transmission Assemblies

Abstract

An Intelligent Integrated CAD system applied in mechanical engineering design for selection, calculation and design embodiment of shaft-bearing-gear is presented in the paper. The CAD activities in correlation with the expert system are defined according to a given expertise domain, design of mechanical systems, which is supposed to take into account and operate with two information type: knowledge and data. Final results and concrete example are performed using CAD/CAE/CAM software, CATIA environment. Knowledge and databases processing for application presented in this paper use specific programming environment expert systems, Prolog – Flex. For user interface Visual Basic programming language is used, and Excel for data and knowledge base, which integrated in CATIA environment. Data transmission between the two performance programs CATIA and Prolog is made through the Excel files
