Abstract

A number of analytical and numerical approaches are available for the analysis of journal bearing under different mechanism of wear, fatigue and crush during service conditions. The present work deals with the variation of different parameters like coefficient of friction, bearing modulus, flow variable with respect to the bearing characteristics number(S). With the help of above parameters, the effect of eccentricity for journal and bearing on the design aspects can easily be encountered. The results revealed that the bearing parts should have appropriate clearance, pressure distribution and a range of eccentricity ratio should be maintained for proper operation of journal bearing apparatus. Furthermore, deep numerical analysis of the complete experimentation suggests the need of evaluating the above design parameters in detail. The article also aims also to provide the efficient way to perform the experiment taking in consideration of calibration and accuracy of the system.

Keywords: Bearing Characteristics Number, Coefficient of Friction, Bearing Modulus and Flow Variable
