Problems solved by technology
This technology controls the output pressure of the tested hydraulic pump by controlling the output torque of the hydraulic motor. It is not suitable for the hydraulic energy system where the tested object is a constant pressure variable pump. By controlling the hydraulic motor, the flow load simulation required by the hydraulic energy system cannot be realized. Function

The invention provides a hydraulic energy system testing apparatus. The testing apparatus comprises a control valve, a hydraulic motor, a load simulation controller and a transmission controller. One end of the control valve is connected with a pressure supply port of a hydraulic energy system, the other end of the control valve is connected with one end of the hydraulic motor, and the other end of the hydraulic motor is connected with an oil tank. The control valve is electrically connected with the load simulation controller, and a motor connected with a hydraulic pump in the hydraulic energy system and a motor connected with the hydraulic motor are jointly controlled through the transmission controller in a concentrated manner. According to the hydraulic energy system testing apparatus, the implementation difficulty of a flow load simulation module in an original testing table is reduced; and meanwhile, energy generated by the hydraulic motor is recycled, and the testing energy consumption is reduced.0.
Description
technical field [0001] The present disclosure relates to a hydraulic energy system, in particular to a hydraulic energy system test device. Background technique [0002] During the development of the hydraulic energy system, it is necessary to build a hydraulic energy system test device for a large number of tests. The device at least includes a complete tested hydraulic energy system, a hydraulic pump drive module and a flow load simulation module. For example, in a hydraulic energy system test device for an aircraft, the hydraulic pump drive module controls the tested constant pressure variable pump to simulate aircraft takeoff, cruise, landing and other working conditions. The flow load simulation module truly simulates the flow changes of systems such as rudder surface action, landing gear retraction, and cargo door opening and closing under different flight conditions. At present, the flow load simulation module is generally implemented by proportional control valves....
