Vibration interaction characteristics of disks-spindle

The purpose of this paper is to develop both numerical and experimental way that can be effectively used for vibration interaction prediction of the disk-spindle systems in HDD. First, the work focuses on the effective modeling method for the analysis of the vibration interaction of whole disks-spindle system. Second, the analytical results had been verified through the proposed experimental method using externally induced excitations for disk-spindle system in product assembly. The two set results agree very well. As shown, the numerical modeling and experiment methods can provide much information on design before to make hardware and verify it in lab.
