- Abstract
- This study investigates the dynamic characteristics of a spinning disk with angular misalignment using
finite element method. The angular misalignment in this study is defined as the angle between the axis parallel
to the shaft and the axis perpendicular to the disk. The angular misalignment is one of major vibration sources
in optical disk drives such as CD-ROM, CD-R, CD-RW and DVD drives. Based upon Kirchhoff plate theory
and von-Karman strain theory, three coupled non-linear equations of motion for the spinning disk with
angular misalignment are obtained. After transforming these equations into weak forms, the weak forms are
discretized by using annular sector finite elements. Applying perturbation method on the discretized equations,
natural frequencies of the disk are calculated and the effects of the angular misalignment on the natural
frequencies are analyzed. The results show that the angular misalignment causes the mode split of the
degenerate modes of the disk.
