An expert system for the design and selection of ball bearing parameters

Artificial Intelligence (Al) is an emerging technology. Research in Al is focused on developing computational approaches to intelligent behavior. The computer programs with which Al could be associated are primarily symbolic processes associated with complexity, ambiguity, indecisiveness, and uncertainty. One of these computer programs is referred to as Knowledge-based Expert System as it represents knowledge acquired from various experts in a particular field of interest to the user. The expert system emulates human behavior in solving problems thought to require experts for their solution by utilizing computer programs that incorporate experts’ heuristic reasoning. In this paper, the application of Knowledge-based Expert System to aid the design of ball and roller bearings is discussed. The precision rolling-element bearings of twentieth century is a product of exacting technology and sophisticated science. A bearing supports radial and axial loads, at the same time allowing relative motion between two elements of a machine. Various requirements and steps in the design of ball and roller bearings are discussed. Equations are developed for the relevant design parameters and input into the expert system shell called VP-Expert. The expert system rules are also provided.
