Variable control characteristic working condition simulation real-time detection system of swash plate type variable axial plunger pump and variable control characteristic working condition simulation real-time detection method

The invention provides a variable control characteristic working condition simulation real-time detection system of a swash plate type variable axial plunger pump and a variable control characteristicworking condition simulation real-time detection method. The detection system comprises a detected pump and a model pump, a plunger pressure sensor is mounted in a piston cavity of the detected pump,angular displacement sensors are mounted on swash plates, oil pressure sensors are mounted in variable piston cavities, the model pump and the detected pump are same in structure and size, mounting positions of parts are same, the model pump replaces a detected pump plunger of the detected pump with an electric push rod set, an oil outlet of the detected pump is provided with a pilot valve, the valve is used for adjusting the flow entering variable pistons of the detected pump and the model pump, angular displacement of the detected pump swash plate feeds back the output flow of the detectedpump, thrust of electric pu
