Abstract: Considering the anisotropic characteristics, layup angle, thickness and sequence of composite material, the dynamics model of multilayered composite large fan blade is established. The natural frequency and mode of composite blades are calculated based on the modal analysis method, and the response characteristics of the blades are studied by harmonic response analysis method. The Campbell diagram is used to analyze the natural characteristics of the blades at different speeds. The influence of laying parameters on the vibration characteristics is studied for the composite fan blade. The results show that by adjusting the thickness, angle and sequence of the composite blades, the resonance point and the amplitude can be reduced to achieve the damping effect.

Key words: laying parameters, composite material, large fan blades, vibration characteristics
