Aiming at the shortcomings of common wind turbine blade fatigue loading methods, a new fatigue loading method based on motor-drum-traction rope drive is proposed, and single-axis and dual-axis loading control strategies are designed. Firstly, the dynamic analysis of the fatigue loading system based on the traction rope is carried out, and the feasibility of the half-wave simple harmonic periodic excitation force is illustrated. Secondly, the uniaxial loading control with dynamic update of the excitation force amplitude and excitation frequency is designed. Finally, the co-simulation analysis of Adams and MATLAB is used to verify the rationality of the dual-axis loading control strategy, which provides a basis for future research on the fatigue loading system based on traction rope.
