Abstract

A storage device test slot includes a housing. The housing defines a test compartment for receiving a storage device for testing. One or more tuned mass dampers are connected to the housing. The one or more tuned mass dampers are configured to inhibit vibration of the housing at one or more predetermined frequencies.

Claims

1. A storage device test slot comprising:

a housing defining a test compartment for receiving a storage device for testing; and

one or more tuned mass dampers connected to the housing, the one or more tuned mass dampers being configured to inhibit vibration of the housing at one or more predetermined frequencies.

2. The storage device test slot of claim 1, wherein the one or more tuned mass dampers comprise a beam connected to the housing.

3. The storage device test slot of claim 2, wherein the beam is integrally connected to the housing.

4. The storage device test slot of claim 2, wherein the beam comprises two or more layers that are configured to slide relative to each other.

5. The storage device test slot of claim 2, wherein the beam comprises a cantilever beam.

6. The storage device test slot of claim 2, wherein the one or more tuned mass dampers further comprise a weight connected to the beam.

7. The storage device test slot of claim 6, wherein the weight is integrally connected (e.g., molded, machined, or otherwise formed with) to the beam.

8. The storage device test slot of claim 6, wherein the one or more tuned mass dampers further comprise a layer of energy absorbing material disposed between the beam and the weight.

9. The storage device test slot of claim 8, wherein the energy absorbing material is selected from a group consisting of:

an elastomer, a viscoelastic adhesive, and a viscous liquid.

10. The storage device test slot of claim 8, wherein the one or more tuned mass dampers further comprise a layer of substantially rigid material fixed to a surface of the energy absorbing layer.

11. The storage device test slot of claim 1, wherein the one or more predetermined frequencies are associated with one or more vibration modes of the housing.

12. The storage device test slot of claim 1, wherein the test compartment is configured to receive and support a storage device transporter carrying a storage device for testing.

13. The storage device test slot of claim 1, wherein the one or more tuned mass dampers are connected to an outer surface of the housing.

14. The storage device test slot of claim 1, wherein the one or more tuned mass dampers are connected to an inner surface of the housing.
