| Abstract: |
| The work aims to propose a full state examination method for the typical hydraulic pipeline of aircraft and consider the coupling response of high-pressure and high-speed flow of hydraulic oil in the hydraulic pipeline and the external vibration environment. Firstly, the specimens of hydraulic pipeline and its support structure were extracted from the hydraulic pipeline system of the typical cabin to simulate the support stiffness of aircraft structure for installing hydraulic pipeline. Then, the hydraulic loop module was used to simulate the flowing environment of hydraulic oil in the hydraulic pipeline and the vibration test module was adopted to simulate the main factors influencing the fatigue life of two hydraulic pipelines in the aircraft cabin and the vibration environment. The main factors influencing the fatigue life of hydraulic pipeline could be applied at the same time through the designed test. For the big difference between the ground test and the actual flight state of aircraft hydraulic pipeline, a full state examination and test method for the typical hydraulic pipeline of aircraft is proposed and the test provides an important basis for the vibration reduction optimization design of the aircraft hydraulic pipeline. |
