According to the dynamic load analysis method for the multi-axis rotating equipment installed on the airplane, the multi-axis rotating equipment comprises a rotating part A and a rotating part B, the rotating part A is rotationally connected with an airplane structure, and the rotating part B is rotationally connected with the rotating part A. A kinematic model of the multi-axis rotating equipment is established; describing a motion rule of the multi-axis rotating equipment along with time change under a machine body reference coordinate system; establishing a mass model for describing each rotating part under a body reference coordinate system, and describing block mass characteristics of each mass block of each rotating part under the body reference coordinate system, a mass center model of each mass block and a rule of moment of inertia of each mass block changing along with time; according to the principle of theoretical mechanics, the additional dynamic load of each rotating component in a fuselage reference coordinate system is calculated by considering the motion parameters and the quality characteristics of the multi-axis rotating equipment at fuselage mounting points, and the time-varying load and the dynamic response parameter of each rotating component can be calculated in the air gust flight environment when the elastic response of the fuselage is considered.
