Optimisation of Pressure and Oil Film Thickness in Multilobe Bearing using Response Surface Methodology and Moga

Abstract

The performance of a bearing depends upon its load bearing capacity without compromising the friction. As the load increases, oil film thickness decreases owing to increase in oil pressure causing an adverse effect on bearing performance. In multi-lobe bearing oil pressure is released by draining the oil through the lobes. Thus, an optimum oil film thickness can be maintained while increasing the load bearing capacity. An attempt has been made to optimize the oil film thickness after satisfying the condition of maximizing the pressure in three lobes bearing using a genetic algorithm. It gives optimum result and their respective parameter configuration.
