N2 - This paper proposes a dynamic lubrication model for the slipper/swash plate pair of the high-speed electro-hydrostatic actuator (EHA) pump. A single slipper motion mode was analyzed firstly, as well as an extra forth drift motion of the slipper was presented based on the reason that, the slipper center of mass would rotate around the piston ball joint center when the swash plate angle changes. And then, detailed forces and moments analysis for the slipper/swash plate pair are performed. According to the theorem on translation of force, extra tilting moments would be produced for the slipper and the tilting inertia moments would increase rapidly when the EHA pump operating in high speed. Finally, based on the slipper external force module analysis, a dynamic lubrication model coupling oil film thickness field was developed, the impact of transient characteristics on the lubrication oil film thickness was also explored and validated by massive simulation results.
