Abstract

Although surface texture has been becoming an attractive technique for improving hydrodynamic performance in lubrication system, the study of surface texture mainly focus on the steady-state load conditions. This investigation evaluates the effect of surface texture on hydrodynamic performance under transient lubrication in parallel bearing. In the case, considering cavitation phenomena in liquid lubricating film, a mass conserving formulation based on Elrod–Adams model with JFO conditions is then employed. The implementation of numerical simulation is discretized in spatial and time domain for calculating the pressure distribution. The effect of different geometrical configurations of lubricated contact on hydrodynamic performance is evaluated. The results show that surface texture in parallel bearing yields a great improvement in terms of friction force and friction coefficient.
