Optimization of texture of the multiple textured lubricated contact with slip

Abstract

Development in surface modifications including texturing and boundary slip has shown promising outcomes in enhancing the hydrodynamic lubrication performance. In this work, the modified Reynolds equation was considered in order to evaluate the tribocharacteristics of partially textured contact with boundary slip. Finite volume method coupled with tridiagonal matrix algorithm was used to solve non-linear Reynolds theory. For maximizing the load support, the optimization procedure was carried out using the exact optimization method. Results showed encouraging improvements in load support behaviour by shifting the multiple-texture to exit zone of the contact. It was also confirmed that the improvement of the load support of around 300% using the optimized textured lubricated contact could be achieved.
