Elliptical microtexture array Oil film characteristics Orthogonal design Response surface analysis Lubrication performance The axial piston pump is a type of positive displacement variable pump that alters the volume of the piston chamber by driving the pistons in a reciprocating motion through...

... that the GA-SVM prediction model has the smallest error for FC, WR and WL, showing that it owns excellent prediction accuracy. The predicted values obtained by response surface analysis are closed to those of GA-SVM model, providing further evidence of the validity and the rationality of the established...
