Abstract

An energy absorbing restraint device for a clamp system is disclosed. The clamp system can include a releasable clamp having first and second ends, a securing mechanism connecting the ends and facilitating clamping and release of the clamp, and a restraint device for containing the clamp after release. An energy absorbing member supported about the restraint device can be configured to interface with the releasable clamp to dissipate the impact energy of the releasable clamp and decrease the magnitude of impact shock about the restraint device as created by the release of the clamp.

Claims

1. A clamp system comprising:

a releasable clamp having first and second ends disconnected from one another, the releasable clamp operable to apply a clamping force to secure one or more bodies;

one or more restraint devices operable to limit the displacement of the releasable clamp upon release of the releasable clamp;

a securing mechanism connected to the first and second ends of the releasable clamp, and operable to facilitate clamping and release of the releasable clamp; and

an energy absorbing member supported about the restraint device, and operable to interface with the releasable clamp to dissipate an impact energy of the releasable clamp upon release of the securing mechanism and displacement of the releasable clamp.

2. The clamp system of claim 1, wherein the energy absorbing member dissipates the impact energy of the releasable clamp through plastic deformation.

3. The clamp system of claim 1, wherein the energy absorbing member comprises a honeycomb structure.

4. The clamps system of claim 1, wherein the honeycomb structure comprises a metallic makeup.

5. The clamp system of claim 1, wherein the honeycomb structure comprises aluminum.

6. The clamp system of claim 1, wherein the energy absorbing member is located at a location where the release energy of the releasable clamp about the restraint device is the greatest.

7. The clamp system of claim 1, wherein the energy absorbing member is located at a location substantially adjacent the securing mechanism.

8. The clamp system of claim 1, wherein the energy absorbing member is supported about the restraint device by an adhesive.

9. The clamp system of claim 1, wherein the releasable clamp comprises a v-band clamp.

10. A clamp system comprising:

a first body;

a second body operable to interface with the first body, the first and second bodies being separable from one another;

a releasable clamp operable to apply a clamping force about at least one of the first and second bodies;

one or more restraint devices secured to at least one of the first and second bodies, and operable to retain the clamp about at least one of the first and second bodies; and

an energy absorbing member supported about at least one of the restraint devices and operable to interface with the clamp to dissipate an impact energy of the clamp upon release and displacement of the clamp.

11. The clamp system of claim 10, wherein the energy absorbing member dissipates the impact energy of the releasable clamp through plastic deformation.

12. The clamp system of claim 10, wherein the energy absorbing member comprises a honeycomb structure.

13. The clamps system of claim 12, wherein the honeycomb structure is aluminum.

14. The clamp system of claim 10, wherein the energy absorbing member is located at a location where the release energy of the releasable clamp about the restraint device is the greatest.

15. The clamp system of claim 10, wherein the energy absorbing member is located at a location substantially adjacent a securing mechanism.

16. The clamp system of claim 10, wherein the energy absorbing member is supported about the restraint device by an adhesive.

17. The clamp system of claim 10, wherein the releasable clamp is a v-band clamp.

18. A method for facilitating absorption of an impact energy of a releasable clamp, the method comprising:

providing a releasable clamp;

providing one or more restraint devices operable to limit the displacement of the releasable clamp upon release of the releasable clamp;

providing a securing mechanism connected to the first and second ends of the releasable clamp, and operable to facilitate clamping and release of the releasable clamp; and

providing an energy absorbing member supported about the restraint device, and operable to interface with the releasable clamp to dissipate an impact energy of the releasable clamp upon release of the securing mechanism and displacement of the releasable clamp.

19. The method of claim 18, further comprising configuring the energy absorbing member to dissipate the impact energy of the releasable clamp through plastic deformation.

20. The method of claim 18, wherein the energy absorbing member comprises a honeycomb structure.

21. The method of claim 18, wherein the releasable clamp is a v-band clamp.

23. The restraint device of claim 21, wherein the energy absorbing member comprises a honeycomb structure.

22. A restraint device configured to absorb an impact energy of a clamp, the restraint device comprising:

a body having a receiving surface;

an energy absorbing member supported about the receiving surface, and operable to undergo plastic deformation in response to a load,

wherein the energy absorbing member comprises pre-crush initiators to facilitate optimum dissipation of energy through progressive localized buckling.

24. The restraint device of claim 22, wherein the honeycomb structure is aluminum.
