Method and apparatus for providing a fluid damping structure with fuel cell for a hard disk drive and vibration sensitive electronic devices

摘要

A shock and vibration resistant hard disk drive has a plurality of fluid damping isolation devices disposed between the drive and a supporting frame. The isolation devices are capsules containing either gasses or liquids enclosed in a flexible membrane that spring back to its original shape after the shock or vibration event has transpired. Variation of fluid properties such as density, viscosity, and pressure allow for custom tuning of the vibration and shock performance. In addition, variation of membrane chemistry and thickness of the membrane also allows for further customization. A fuel cell is provided and the isolation devices may provide the energy source for the fuel cell.
