Abstract
In this study, we propose a tribo-dynamic model of slipper bearings in axial piston pumps and motors. We construct a unified model that considers the interaction between tribological behavior and dynamic performance. A niche genetic algorithm method is used to solve the model. The effects of cylinder speed, loading pressure, and oil viscosity on the behavior of the slipper are outlined. A test bench is established for the measurement of the slipper film thickness. We demonstrate that the elastic deformation, wearing profile, and hydrodynamic effect should be considered in the model. A high loading pressure and low speed with low viscosity will result in a low film thickness and severe tilting.
