“…Jang et al [4] carried out a free-vibration analysis of a spinning flexible disk-spindle system supported by a ball bearing and a flexible shaft using the finite-element method and substructure synthesis. Lee [5] and Lim [6] examined the coupled vibration of disk-spindles in the context of hard-disk drives. Parker [7] and Parker and Sathe [8] formulated the rotating-system problem in terms of extended operators that make the gyroscopic nature of the system evident.…”

Free vibrations of a spinning disk-shaft system are analysed using the finite-element method. The spinning disk is described by the Kirchhoff plate theory. The shaft is modelled by a rotating beam. Using Lagrange's principle and including the rigid-body translation and tilting motion, equations of motion of the spinning flexible disk and shaft are derived consistently to satisfying the geometric compatibility conditions on the internal boundaries among the substructures. The finite-element method is then used to discretize the derived governing equations. The method is applied to the shaft-disk spinning system. The sensitivity to the running speed as well as the effect of both disk flexibility and boundary condition on the natural frequencies of the spinning system are numerically investigated.

“…However, the heat transfer and flow characteristics, the temperature distribution in the hard disk drive tester are significantly factors to the failure of the hard disk drive while testing process. Lim [1] analyzed the vibration of the hard disk drive spindle system by the finite element method. The proposed method can be applied for designing HDDs and the various other high performance computer disk drives.…”

“…On the other hand, Lim [5] has investigated the dynamics of the spinning #exible disk}spindle system by using the "nite element method and substructure synthesis. He described the disk with a linear model and he did not include the #exibility of the stationary shaft.…”
