Abstract
Wear failure of the slipper pair limits axial piston pump life. Most of the current slipper wear models ignore or assume certain factors, resulting in poor calculation accuracy. To better reveal the lubrication and wear laws of slipper pairs, a lubrication-wear dynamic interaction model (LWDIM) is proposed. The slipper considers the effects of tilt and rotation, the impact of fluid–solid–thermal coupling on the viscosity of oil, and the impact of the induced elastic and thermal deformation of the slipper surface on the oil film thickness. In addition, the rough surface contact model is introduced to consider the effects of rough contact force on the support of external loads and surface wear, as well as the impact of rough surface distribution and wear height on the oil film thickness. The considered multifactor is dynamically fed back to update and resolve the oil film thickness and wear distribution. The lubrication characteristics and wear patterns of the lower boot under various working conditions are analyzed by numerical simulation. Experiments show that the mean absolute error (MAE) of the oil film thickness is 0.1 μm, and the MAE of the wear height is 0.83 μm, of which the mean relative error (MRE) of the oil film thickness is only 3.27%, which effectively verifies the calculation accuracy.
