The invention provides a performance test experiment table for a high-pressure aviation hydraulic pipeline, and the experiment table comprises a hydraulic pump station which comprises an oil tank, a fixed-displacement hydraulic pump, a motor, a high-pressure valve group, an energy accumulator, and a sensor assembly; the aviation hydraulic pipeline to be tested is connected with the pump station through a stainless steel pipeline and a high-pressure hose; the control system comprises an electric control cabinet and a controller; a load loading system comprises a vibration load loading device, a temperature load loading device and a displacement load loading device which can be superposed with a high-pressure load provided by the pump station; and a joint assembly comprises a stop valve and a pressure sensor and is used for assisting in controlling the pressure of an experiment table and playing a role in monitoring the pressure. The experiment table can carry out pressure, vibration, temperature and displacement load loading on the high-pressure aviation hydraulic pipeline, conforms to the actual working condition of the aviation hydraulic pipeline, is high in control precision and can collect various load data. And meanwhile, temperature control is good, and the fault problem caused by too high system temperature under high pressure can be prevented.
