Abstract

In order to get a better understanding of head to flexible disk interface problems, Green's function for a spinning flexible disk deflection is derived by extention of the analytical method proposed for a stationary flexible disk in the previous paper. As a result, it is found that a flexible disk has many resonance speeds where each circumferential mode component is excited by a stationary force. The external stiffness has the effect of increasing these resonance speeds whereas the external damping makes the disk deflection asymmetric with respect to the applied force. Theoretical results are roughly verified by the experiments.
