| Abstract: | In fatigue tests of landing gears,points at which loads are applied would usually move,as units under test are deformed under load.A loading device for fatigue test of landing gears is developed in this paper to provide a solution to the displacement of load applying point with deformation of unit under test.The structure layout and operating principle of the loading device are described and the application of the device to the fatigue test of the landing gear for an aircraft is discussed. |
