The working performance of aircraft flap system directly affects the safety and maneuverability of the aircraft. Therefore,the aircraft flap hydraulic system is taken as the research object, and it is modeled and simulated by applying AMEsim software.The working principle of the aircraft flap hydraulic system is studied and its common faults are analyzed. The hydraulic system fault simulation is realized by changing the parameters of the hydraulic system, the fault characteristic parameters of the aircraft hydraulic system are determined, and the variation characteristics of the signal to be tested of the aircraft flap hydraulic system under fault conditions are studied. Thereby, the physical simulation can be effectively reduced, the test cost is reduced, and the design efficiency is improved.
