Simulation Analysis and Fault Simulation of Aircraft Landing Gear Retraction Hydraulic System based on Model

In this paper, the AMEsim software is used as the simulation platform to study the retraction hydraulic system of aircraft landing gear. The composition and working principle of the aircraft landing gear retraction hydraulic system are introduced. Then, the retraction hydraulic system model of the aircraft landing gear is established by using the hydraulic library, hydraulic component library, and mechanical library provided by the AMEsim software, and the simulation analysis method is used. By changing the parameters of the hydraulic pump, oil filter, retractable actuator, electromagnetic directional valve and other modules, the failure of the corresponding module is simulated and its influence is analyzed.
