    摘要: Machine tools combine material addition via ultrasonic object consolidation and subtractive techniques for imparting high-dimensional accuracy to a finished object. A material supply and feeder, ultrasonic horn, and feedstock cutting device are integrated with a material removal subsystem preferably including a cutting tool and an excess material removal system. Any metal, plastic or composite material suitable for ultrasonic joining may be employed as a feedstock, and these material may assume the form of tapes, sheets, wires, filaments, dots or droplets, with the feeding and material cutting components being designed for the specific feedstock employed. The cutting tool for excess material removal, may be a knife, drill/mill, grinding tool, or other tool capable of accurately cutting the external contour of a cross section of the part being built, and for removing excess feedstock remaining following the application process. The material removal could consist of a vacuum or blower system, chip auger, or other suitable apparatus. A machine disclosed as part of the preferred embodiment is able to deposit material in one step, and optionally and selectively remove it in another. Through the expeditious combination of deposition and removal, the fabrication of objects of arbitrary shape may be realized.

    摘要: A continuous, single-step, low-temperature process combines metal coating with the splicing of fibers, producing a single, continuous low-cost process for embedding fibers in metal, and/or the splicing of fibers with a joint featuring uniform composition and high strength requiring no additional adhesives. The method can be used to create terminations for cables, or it can be used as a method of splicing or joining optical fibers by positioning the ends of the two fibers under the foils, so that they abut prior to creating the bond. The consolidation material may be provided in sheets, with or without fiber-locating grooves or, alternatively, droplets may be used. In the preferred embodiment, ultrasonic vibrations are used as the source of consolidation energy. A range of metals are suited to the process, including aluminum, copper, titanium, nickel, iron and their alloys as well a numerous other metals of more limited structural utility.

    摘要: A system and a method of fabricating a three-dimensional object on a substrate includes adding material layers incrementally and consolidating the layers by using ultrasonic vibrations and pressure. The layers are placed in position to shape the object by a material feeding unit, and they come in various forms, including flat sheets, segments of tape, strands of filament or single dots of material. The material may be plastic or metallic, and composition may vary discontinuously or gradually from one layer to the next, creating a region of functionally gradient material. The invention permits the construction and repair of dense objects, including fiber-reinforced composites and aerospace structures. Excess material may be removed one or more layers are bonded, including following end of the process after the final object is fabricated. The layers are fed sequentially and additively according to a layer-by-layer computer-model description of the object, which is generated by a computer-aided design/manufacturing (CAD/CAM) system. Ultrasonic welding equipment applicable to the invention preferably includes an ultrasonic generator, a transducer, a booster and a head unit or sonotrode.

    摘要: A system for electro-hydrodynamically extracting energy from wind includes an upstream collector that is biased at an electric potential and induces an electric field. An injector introduces a particle into the electric field. The wind drag on the particle is at least partially opposed by a force of the electric field on the particle. A sensor monitors an ambient atmospheric condition, and a controller changes a parameter of the injector in response to a change in the atmospheric condition.

    摘要: Solid-state bonding technologies are combined with other solid-state consolidation techniques to create new processes, applications, and structures. One embodiment uses metal or plastic spraying techniques with the intention of only partially bonding the droplets to the substrate, while employing a secondary process such as ultrasonic and/or electrical resistance consolidation to achieve complete agglomeration and eliminate porosity. This opens new opportunities with regard to materials, powder types, applications, and automated machinery. Some examples of these hybrids and their applications are provided, however, along with the identification of other combinations.

    摘要: In ultrasonic object consolidation, the location of the sonotrode may be independent, and selected (like other processing parameters such as amplitude, frequency, force, and speed), for optimum processing. According to one preferred embodiment, the improvement includes welding certain regions of the object multiple times. Alternatively or in conjunction with other steps, the method includes the act of selecting sonotrode position to minimize bulk motion of the object. The invention improves upon the existing art by optimizing the positioning of the sonotrode relative to the geometry. This may, for example, comprise independently positioning the horn to treat one or more features within a cross section of the object differently, or determining tape placement location and tacking the feedstock in advance of welding. The feedstock may be provided in any suitable form, including wires, tapes and dots.

    摘要: Fibers and layers are co-applied using ultrasonic consolidation and providing steps and/or materials to maintain collimation of the fibers. According to one preferred embodiment the mechanism is a scrim. Alternatively the mechanism may include a material having one or more fibers under a foil layer. The mechanism may further include embedding a layer of fibers in a foil in a “tacking” process, and consolidating the result with an underlying substrate. Yet a further alternative includes interspersing metal fibers between reinforcing fibers. The reinforcing fibers may include SiC, B or Al2O3 fibers. A different preferred method of co-applying fiber and metal using ultrasonic consolidation, comprises the steps of alternating either an encapsulation material or another metal with optical, ceramic, shape-memory, or other fibers of interest, and encapsulating the result between layers of foil.
