In particular, the present invention relates to apparatus and methods of vibration for tooling in a structure, such as, for example, a fuselage. In one implementation, the tooling comprises at least two conductors that create a force to vibrate the media in the tooling, which improves the compaction of the media in the tooling and the extraction of the media from the tooling. Other implementations may be used for compaction and/or extraction of the media in the tooling.
I. CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Provisional Application No. 60/397,022, filed Jul. 22, 2002, by Curtis Longo and titled VIBRATION APPARATUS AND METHODS OF VIBRATION, the disclosure of which is expressly incorporated herein by reference.
II. BACKGROUND A. Technical Field
III. SUMMARY OF THE INVENTION An apparatus consistent with the present invention provides a vibration apparatus for tooling. The vibration apparatus includes a container comprising a top surface, a bottom surface, a first layer of elastomeric material located on the bottom surface, a first conductor located in the first layer, a second layer of elastomeric material on the first layer, and defining a space between the first layer and the second layer, a second conductor located in the second layer in proximity to the first conductor; and a cavity located between the top surface and the second layer.
IV. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and, together with the following description, serve to explain the principles of the invention.
FIG. 9 is a perspective view of a mandrel form created on a mandrel consistent with an embodiment of the invention, as shown in FIGS. 8A�8E;
FIG. 11 illustrates removing a mandrel from a mandrel form consistent with an embodiment of the present invention, as shown in FIGS. 10A�10C.
V. DESCRIPTION OF THE EMBODIMENTS A. Introduction
In this implementation, process 500 begins with start 510. After start 510 is prepare mandrel 520. In this implementation, prepare mandrel 520 comprises the selection of the size, shape, and type of mandrel to form the fuselage (such as fuselage 300). Prepare mandrel 520 is further described in FIGS. 6A�6B.
In this implementation, form mandrel 530 is followed by fill with media 540. Fill with media 540 comprises filling the mandrel with filler media, such as ceramic spheres available under the product name Macrolite. Fill with media 540 may also comprise compacting the media. Fill with media 540 is further described in FIGS. 8A�8E.
In this implementation, form part around mandrel 550 is followed by remove media 560. Remove media 560 comprises the extraction of the media from the mandrel. Remove media 560 may also comprise dislodging any compacted media. Remove media 560 is further described in FIGS. 10A�10C.
As further shown in FIG. 6B, in this implementation, spacing layer 640 is located between first conductor layer 630 and second conductor layer 650. If an electrical charge is placed on first conductor layer 630 and second conductor layer 650 (as described in more detail below), spacing layer 640 provides an area for layers 630, 650 to flex apart, as further described in FIGS. 8A�8E.
As still further shown in FIG. 6B, in this implementation, media cavity 660 is between top of media cavity 662 and bottom of media cavity 663. If a charge is placed on first conductor layer 630 and second conductor layer 650 as described above, media cavity 600 also provides an area that may be flexed apart, as electrical currents are passed through conductors 670 and 680, as further described in FIGS. 8A�8E.
With reference to FIG. 8B, in one implementation, during the introduction of media 820, media 820 may be compacted to settle the media and to make mandrel 600 more rigid. The amount of compaction may depend on the particulate size of media 820. For example, if media 820 can be broken into smaller pieces during the filling process, space located in clumps of media 820 may be removed, which would allow for greater compaction. Also, as described in FIGS. 8C�8E (below), conductors 670 and conductors 680 may be used to achieve compaction. This implementation is merely exemplary, and other materials and implementations may also be used.
With regard to the displacement, as shown in FIG. 8C, in this implementation, controller 860 creates a current flow in conductors 880 in one direction, while controller 870 creates a current flow in conductors 890 in an opposite direction. As shown in FIG. 8C, the resulting magnetic fields around conductors 880 and conductors 890 result in a repulsive force, which forces conductors 880 and conductors 890 apart. This repulsive force results in a vibration of conductors 880 and 890. When these conductors are placed in a mandrel, such as mandrel 600, this will cause a �vibration� over a large portion of the interior of the mandrel. This implementation is merely exemplary, and other materials and implementations may also be used.
FIG. 9 is a perspective view of a mandrel form created on a mandrel consistent with an embodiment of the invention, as shown in FIGS. 8A�8E. As shown in FIG. 9, composite part 950 has been formed around mandrel 600. Prior to formation of composite part 950, form tool 710 is removed. After removal of form tool 710, mandrel 600 will retain its desired shape due to media 820 contained in bag 610, which is held under vacuum. Composite part 950 may then be created around mandrel 600.
FIG. 11 illustrates removing a mandrel from a mandrel form consistent with an embodiment of the present invention, as shown in FIGS. 10A�10C. As shown in FIG. 11, following removal of the media (as shown above) and after the removal of armature 620 from composite part 950 (not shown), bag 610 is also removed from composite part 950. In one implementation, conductors 680 and 670 (not shown) may be once again energized to facilitate separation of bag 610 from fuselage 950. In another implementation, another set of conductors may be positioned in an elastomeric subassembly that would be fitted around fuselage 950. In this implementation, instead of acting from the interior of the assembler this implementation would act on the exterior of composite part 950 to aid in extraction of bag 610. Still other implementations may also be used. These implementations are merely exemplary, and other implementations may also be used.
VI. CONCLUSION As described above, therefore, other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims and their equivalents. In this context, equivalents mean each and every implementation for carrying out the functions recited in the claims, even if not explicitly described therein.
