More Information
Summary:The speed regulation fundamental principle of fixed displacement pump-variable displacement motor system was described. The control modes of flow feedback were analyzed, given integral controller for getting constant rotational speed output control. The AMESim simulation model of the system was Built, analyzing the influences of relevant factors on constant speed output control, such as the load torque, rotational speed input, load inertia, and high pressure accumulator. It provides theoretical basis for designing the constant speed output system of fixed-displacement pump, variable-displacement motor.
