【Abstract】 Operation principle of digital pump is introduced and the static and dynamic mathematical models of its system are developed for the axial piston pump A4V of Rexroth company, Germany. Using the developed mathematical models and available simulation software MATLAB, the system programming is performed and the static and dynamic responses of this digital pump with constant power are obtained. The pattern of influence of parameter change in piston diameter of the pump is obtained by means of simulation analysis.更多还原
