Flapwise Bending Vibration Analysis of Rotating Cross-ply Composite Beams

전단 및 단면 관성효과를 고려한 Cross-ply 복합재 회전 외팔보의 면외방향 굽힘 진동해석

A modeling method for the modal analysis of a rotating cross-ply composite beam based on Timoshenko beam theory is presented. To analyze the composite beam exactly, the effects of shear deformation and rotary inertia are included. Linear differential equations of motion are derived using the assumed mode method. For the modeling, hybrid deformation variables are employed and approximated to derive the equations of motion. The effects of the dimensionless angular velocity and the slenderness ratio parameter on the variations of modal characteristics are investigated
