摘要：

To study the fluid character of axial piston pump, a mathematical model of flow condition in piston chamber was developed with compressibility of fluid oil. The model was further improved by analysis of movement model of piston, cross area of valve plate, throttle coefficient, flow loss inside pump, etc. Besides, the model of whole piston pump with its hydraulic system was developed with lamped parameter method. A simulation system was built by using Matlab based on the mathematical pump model. A visual graphical user interface was established to automatically analyze the relation between pump geometric structure, working conditions, system parameters and flow conditions of pump. The flow conditions of the pump were tested by using pump flow ripple test rig. It is shown that the pressure pulsation and flow ripple results calculated by the mathematical model agree well with the experimental results. The analytical error can be controlled within 5%. It can be concluded that the developed mathematical model has high precision and can accurately predict the fluid character of axial piston pump.
