The invention discloses a loading method and loading device for an aircraft engine frame fatigue test. The method comprises the steps of setting a plurality of lifting points on a truss structure of the loading device, and respectively simulating the connection between an aircraft engine and an engine frame; and arranging a heading loading support, a vertical loading support and a lateral loadingsupport on the truss structure of the loading device, and applying course load, vertical bending moment, vertical load, lateral bending moment, lateral load and course bending moment to the loading device. The loading device meets the real gravity center position of the engine, simulates the real connection relationship between the engine and the engine frame, more accurately simulates the loadingcondition of the engine frame in the flight process of an aircraft, and effectively improves the reliability and authenticity of a test result.
