| Abstract: | The vibration modes of thin-walled composite beams with three-cell box sec- tion and airfoil section were studied by the finite element software ANSYS. The finite element models were established first for these composite beams, then the vibration modes were calculated and analyzed. The effects of ply angle, length-width ratio and width-height ratio on the modal shape and the natural frequency of the three-cell com- posite thin-walled box beam and the effects of ply angle, length and layer number on the mode shape and the natural frequency of the airfoil composite thin-walled beam were discussed. |
