Abstract
Reduction methods of flow induced vibration of a head-arm between rotating disks in HDD are examined experimentally by flow visualization of a smoke wind tunnel. Flow condition around enlarged model of head-arm was examined putting a focus on separation of the flow generated around head-arm. The separation can be reduced by optimizing the aspect ratio of the head-arm, the size of hole fabricated in the head-arm. Chamfering front edge of is also effective.
