Abstract

A testing assembly for reducing noise emitted from a random vibration apparatus is provided. The testing assembly comprises a base assembly and a cover assembly hingedly connected to the base assembly. At least one inner base positioned within the base assembly with each inner base having at least one aperture. A vibration testing table is secured within the inner base. At least one vibration mechanism is secured within the inner base and communicates with the vibration testing table.

Claims

1. A testing assembly for reducing noise emitted from a random vibration apparatus, the testing assembly comprising:

a base assembly;

a cover assembly hingedly connected to the base assembly;

at least one inner base having positioned within the base assembly, each inner base having at least one aperture;

a vibration testing table secured within the inner base; and

at least one vibration means for vibrating the testing table, the vibration means secured within the inner base and communicating with the vibration testing table.

2. The testing assembly of claim 1 wherein the base assembly includes a base wall, an outer wall, a middle wall, and an inner wall.

3. The testing assembly of claim 2 wherein the outer wall is constructed from a sheet metal material, the middle wall is constructed from a foam material, the inner wall is constructed from a high density vinyl material, and the base wall is constructed from a sheet metal material.

4. The testing assembly of claim 2 wherein the outer walls are secured to the base wall and each other.

5. The testing assembly of claim 4 wherein the inner walls are secured to each other by a plurality of brackets and are secured to the outer side walls.

6. The testing assembly of claim 2 wherein the middle walls are sandwiched between the outer walls and the inner walls.

7. The testing assembly of claim 1 wherein the inner base is constructed from a sheet metal material.

8. The testing assembly of claim 1 and further comprising:

at least one hinge for connecting the base assembly to the cover assembly.

9. The testing assembly of claim 1 wherein the cover assembly has an inner wall and an outer wall.

10. The testing assembly of claim 9 wherein the inner wall and the outer wall are constructed from a clear plexiglas material.

11. The testing assembly of claim 1 and further comprising:

a resilient gasket between the base assembly and the cover assembly.

12. The testing assembly of claim 1 and further comprising:

a foam panel secured to a rear wall of the cover assembly.

13. The testing assembly of claim 1 and further comprising at least one trim piece about the periphery of the cover assembly connecting the inner wall to the outer wall.

14. The testing apparatus of claim 1 and further comprising:

at least one air manifold for connecting air to the vibration means.

15. An enclosure for receiving a vibration testing table and at least one pneumatic hammer, a device to be tested positionable upon the vibration testing table, the enclosure comprising:

a multi-layered base assembly;

a multi-layered cover assembly positionable upon the base assembly;

a receiving container positionable within the base assembly, the vibration testing table and the pneumatic hammer receivable within the receiving container; and

a plurality of apertures formed in the container.

16. The enclosure of claim 15 wherein the base assembly includes a base wall, an outer wall, a middle wall, and an inner wall.

17. The enclosure of claim 15 and further comprising:

at least one hinge for connecting the base assembly to the cover assembly.

18. The enclosure of claim 15 wherein the cover assembly has an inner wall and an outer wall.

19. The enclosure of claim 15 and further comprising:

a resilient gasket between the base assembly and the cover assembly.

20. The enclosure of claim 15 and further comprising:

a foam panel secured to a rear wall of the cover assembly.
