Spherical swash plate axial piston pump with conical cylinder was taken as research object, the friction power loss, leakage power loss and volumetric efficiency with the change of slipper mechanical structure parameters in slipper film design was analyzed, then the genetic algorithm was used for the multi-variable multi-objective optimization problem. Weighting coefficient optimization results show that after optimization the friction power loss and leakage power loss of the fuel piston pump in design point reduce by about 7%, the volumetric efficiency improves slightly. And the optimized parameters of mechanical structure also show a performance advantage in the cases of different rotor tilt angles and plungers. Thus this proves the multi-objective genetic algorithm is an effective method for the design of hydrostatic pressure lubrication film in aero-engine fuel piston pump.
