In order to realize the precise modeling and optimization design of axial piston pump under the condition of mechanical hydraulic coupling

a method for multidisciplinary coupling modeling and integrated optimization for axial piston pump was put forward. Taking domestic I3V2-10S type axial piston pump as the study object

the mechanical model and the hydraulic model were respectively built in ADAMS and AMESIM. The interface communication between ADAMS and AMESIM was successfully implemented and the simulation of the mechanical and hydraulic coupling models was completed. Besides

in order to achieve the minimum outlet ripple ratio of this pump

the coupling model was integrated by iSIGHT software. The structures in valve plate pair such as oil suction and discharge orifice maximum equivalent diameters

oil suction and discharge dead angles

piston wrap angle

oil suction and discharge pre-opening degree

were optimized in iSIGHT. The results showed that the outlet flow ripple ratio of this pump was reduced by 14.59%

18.57%

23.44%

24.03% and 25.49%

respectively

the correctness of simulation and integration optimization data was verified by experiments.
