Hydrodynamic Bearing Performance Trade-off Study and Fuzzy Based Multi-objective Optimisation on a Offset Surface Textured Journal Bearing

Abstract

ABSTRACT The primary objective of this research is to study the bearing performance characteristics having different operating conditions. Experimental investigations are carried out on phosphorous bronze hydrodynamic journal bearing with a surface textured at different loading conditions with multi-grade oil as lubricating at different constant rotational speeds (i.e.,1000 to 4000 rpm) for studying the dynamic characteristics. Results reported that oil film pressure and temperature distribution profile obtained experimentally are in good agreement with the theoretical results. Fuzzy-based Taguchi optimisation has been used in this experimental analysis to predict the optimal input parameters, which result in the optimal combination of temperature and reported that the oil film pressure and temperature distribution profile obtained experimentally are in good agreement the theoretical results. This analysis also attempts to describe the application of the fuzzy logic-based Taguchi analysis to optimise the performance parameters.
