English Abstract

Different methodologies for designing hydrodynamic journal bearings are reviewed and an integrated and dependable design methodology is developed. Various architectures used in design expert systems are reviewed and an architecture consisting of several stages of grouped rules is employed. The architecture uses a rule-based production system. Relevant objective knowledge is represented appropriately. In this Turbo Prolog program, initially, the user is asked to enter the required prescriptive and functional specifications and the decision-criterion. The design solutions of successive stages are examined for any violations of the design constraints. Utility value of each of the final solutions is calculated and the design solutions having utility values above a certain limit are printed in the output file. The expert system makes an exhaustive search for all the solutions. The results of this expert system are compared with those of the previous workers to illustrate its usefulness.
