Flapwise Bending Vibration of Rotating Timoshenko Beams with Concentrated Mass Moment of Inertia

집중 질량 및 관성모멘트를 갖는 회전하는 티모센코 보의 면외굽힘 진동

A modeling method for the bending vibration analysis of rotating Timoshenko beams with concentrated mass and mass moment of inertia is presented. The shear and rotary inertia effects become critical for the accurate estimation of the natural frequencies and modeshapes as the slenderness ratio decreases. The effect of the concentrated mass and mass moment of inertia on the natural frequencies are also investigated with the modeling method.
