Abstract: An anaysis is presented for investigating the performance of the hydrodynamic inclined fixed pad thrust slider bearing with a normal geometry where the interfacial slippage occurs on the stationary surface in the inlet zone and on the whole moving surface, based on the limiting interfacial shear strength model. The calculation results show that compared with the classical mode of the bearing (without any interfacial slippage), this bearing has a significantly higher load-carrying capacity but a much lower friction coefficient in the same operating condition. The study shows the considerable improvement of the bearing performance by the introduced interfacial slippage.
