Abstract
Free vibration analysis is performed for a spinning disk/spindle system mounted on a flexible baseplate. The disk/spindle system consists of a disk making flexible motion and a spindle making rigid body motions, which are tilting and axial. The governing equation is derived by the assumed mode method and Lagrange's equation. The equation considers effects of baseplate flexibility on the system. By free vibration analysis, the natural frequency variation is investigated versus rotating speed and baseplate thickness. Mode exchange and veering phenomena are attributed to the coupling between the modes of spinning disk/spindle system and baseplate. Finally, Sensitivity analysis is performed by changing the design parameters at the natural frequencies of the disk/rotor system in rocking and axial modes.
