Modeling and dynamic simulation of axial piston variable pump with constant pressure/flow control on waterjet hydraulic system

Based on the principle and requirement of waterjet steering and navigation,the mathematical model of A10VO-DFR axial piston variable pump with constant pressure/flow control is established,as well as the pump simulation model based on Simulink module of Matlab.The study focuses on the correlation between the change of pump output flow and variable rotation speed,load and stop-valve port.The conclusion provides theoretical basis for the performance improvement of the waterjet hydraulic system.
