Simulation of axial piston pump characteristic based on virtual prototype technology

YANG Zhi-wei,XU Bing,ZANG Bin (The Key State Lab og Fluid!Power Transmission and Control, Zhejiang University, Hangzhou 310027, China)  
In order to study the characteristic of piston pump, a virtual prototype of the HAWE V30 piston pump is developed, which is a dynamic simulation method in ADAMS, combined with modeling in Pro/E, flexibility analyzed by ANSYS, and hydraulic modeling in AMESim. The pressure ripple related to the position of swash plate, the pressure pulsations related to pump outlet volume, the kinetic characteristic of the piston, the stress and strain of the shaft are analyzed. Because of its clear physical concept and flexible analysis, the simulation based on virtual prototyping is more convenient for the research into the characteristics of piston pump.
