Optimization of Hydrodynamic Journal Bearing Parameters Using Response Surface Methodology

Mechanical Engineering

The hydrodynamic journal bearing is used extensively in rotating machines because of their low wear and good damping characteristics. Present work has been carried out to obtained the realistic performance characteristics of the journal bearing. The optimization approach which was applied to predict the optimal surface textured parameters to improve efficiency of journal bearing. After studied literatures, some parameters are considered as control parameters viz; groove location, groove width, groove height, number of groove and spacing between grooves for load carrying capacity (LCC) and Frictional Torque (FT) response. The effect various surface textured parameter is simulating for optimum response using the Response surface methodology has been applied. The response surface methodology tool re gives the robust design with respect to the control factors and their level. After the optimization method the comparison have been done with published good literature.
