摘要： An acoustic core has a plurality of cell walls formed of an additive-manufacturing material and a resonant space defined by the plurality of cell walls. At least some of the resonant cells have sound-attenuating protuberances formed of an excess amount of the additive-manufacturing material having been intentionally introduced to the cell walls and protruding into the resonant space with a semi-random orientation and/or size.

摘要： Disclosed is a method for producing an automobile sound absorbing member through molding. In the method, a first fiber and a second fiber are bonded to each other and molded at the same time, so that a working process and a process cycle are simplified, thereby improving production speed and reducing investment for equipment and facility. The method includes (a) preparing a first fiber and a second fiber, (b) providing an adhesive member between the first fiber and the second fiber and placing an aggregate of the first fiber, adhesive member, and the second fiber in a molding machine, and (c) pressing an upper mold and a lower mold of the molding machine so that the first fiber and the second fiber are bonded and molded into a molded body.

摘要： A friction damped insert for highly stressed engineering components is disclosed. The disclosed inventive concept provides a method and system for increasing the damping capacity of an engineering system by adding a non-flat solid, highly damped insert to a system component that contributes most to the system's dynamic response. The insert can either be embedded into a system component during casting or be fastened to the system component outer surface. The insert is made of the single layer of flexible material by forming it into a rigid elongated body. The layer of material can be turned over on itself without folding to create a cylinder or can be folded over a number of times to create a prismatic bar. The layer of material may be shaped into a corrugated panel. The layer of flexible material may have a number of relatively small openings or perforations with a uniform spatial distribution.

摘要： A backing component configured to receive and attenuate transmitted acoustic signals from a transducer element in an ultrasound probe is disclosed. The backing component has a unitary structure of a first material and a second material, and a variation in packing density of the first material across at least a portion of a thickness of the backing component. Further, a method of making a backing component for a transducer element in an ultrasound probe is disclosed. The method includes performing an additive manufacturing technique using a first material and a second material to form the backing component that has a unitary structure of the first material and the second material. Performing the additive manufacturing technique involves varying a packing density of the first material across at least a portion of thickness of the backing component.

摘要： A method for making an insulated vehicle extension dash panel includes injection molding an extension dash panel from a structural polymer. The method further includes adding a plurality of components to a mixer to form an insulating foaming layer. The plurality of components includes a two-part liquid silicone compound, a catalyst, and a foaming agent. A screw is then coupled to the mixer and the insulating foaming layer is injection molded to an inner face of the extension dash panel. The insulating foaming layer is then cured to the inner face of the extension dash panel to form the insulated vehicle extension dash panel.
