    Abstract:

    In order to reduce the friction coefficient of the slipper pair of the miniature-axial piston pump and improve the lubrication performance of the oil film,elliptical micro-texture was designed on the bottom of the slipper shoe,the geometric model of the slipper pair was established,and the oil film pressure field and shear field of the slipper bottom were solved and analyzed by using the flow field simulation.In order to further enhance the effect of dynamic pressure,increase the bearing force and reduce the friction coefficient,the experimental level table was designed by Design-Expert response surface analysis for calculation and analysis.The mathematical model was established with the minimum leakage,maximum bearing force and minimum friction coefficient as the objective functions,and the optimized size of the miniature-texture was finally obtained.After optimization,the oil film lubrication performance of the slipper pair is improved,and the optimized parameters can be used as the basis for structural optimization of the plunger pump.
