This paper is concerned with the #exural vibration analysis of the hard disk drive (HDD) spindle system by means of the "nite element method. In contrast to previous research, every system component is here analytically modelled taking into account its structural #exibility and also the centrifugal

Three-dimensional vibrations of thick circular and annular plates are analyzed by a "nite element method which, with a properly assumed set of displacement "eld, is di!erent from the traditional 3-D "nite element analysis and is reduced to a sequence of 2-D analyses one for each circumferential wave
The equation of motion of a spinning isotropic annular plate of linearly and exponentially varying thickness is formulated based on the Lagrangian approach and the assumed mode method. The plate is assumed to be elastic in the spinning motion and the initial stress fields in the plate are derived as
