Abstract

The application belongs to the technical field of aircraft rear fuselage structure fatigue test, and specifically relates to a fatigue test device, including: two vertical tail vibration load loading devices, and each vertical tail vibration load loading device is used to connect to the aircraft rear fuselage structure correspondingly one vertical tail, to apply vibration load to the corresponding vertical tail; two vertical tail aerodynamic load loading devices, each vertical tail aerodynamic load loading device is used to correspond to a vertical tail connected to the rear fuselage structure of the The aerodynamic load is applied to the tail; the engine frame vibration load loading device is used to connect the engine frame of the rear fuselage structure of the aircraft to apply vibration loads to the engine frame. In addition, it relates to a fatigue test method, which is implemented based on the above-mentioned fatigue test device, and can obtain relatively more effective test results when applied to the fatigue test of the aircraft rear fuselage structure.

Description

technical field [0001] The application belongs to the technical field of fatigue test of aircraft rear fuselage structure, and in particular relates to a fatigue test device and a method thereof. Background technique [0002] At present, when conducting aircraft fatigue tests, the dynamic characteristics of the aircraft structure during flight are mostly ignored, and the load environment of the aircraft structure during flight cannot be truly simulated, resulting in deviations between the test structure and the actual situation. [0003] The rear fuselage structure of the aircraft includes the engine frame and two opposite vertical fins, which are subjected to complex loads during the flight of the aircraft. Among them, the engine frame bears the vibration load caused by the engine when the aircraft is flying, and the vertical fin bears the vibration load caused by the air flow passing through its surface. Vibration loads of eddy currents, as well as withstand aerodynamic lo...
