Vibration Prediction of a Spindle Shaft and Bearing Fitting Assembly Design using Fuzzy Logic

Abstract

This paper proposes Fuzzy Logic for Assembly parts for making a decision and selecting effective fitting for spindle shaft and bearing for each stage of assembly. Multi-criteria decision making is concerned with interference fits, material hardness, surface roughness and spindle force. Assembly needs to concern with the first stage of machined part design which is created by CAD. Fuzzy Logic is applied for effective making decision combined with experts and rules of prediction vibration spindle design modeling. Example cases are illustrated.
