Abstract: A plate assembly for a motor vehicle may include a first plate, a second arranged substantially parallel to the first plate, the second plate defining a plurality of perforations, and a mesh core including a plurality of wire bundles, the core arranged between the plates, wherein the mesh core is rigidly joined to an inner surface of each plate via the perforations.

Abstract: A method and system for improving the vibration damping properties in a metal product are disclosed. The product incorporates a dry friction, layered metallic damping material having embedded therein one or more woven mesh layers comprised of wire ropes of bundled wires. The ropes may be sheathed with a thin layer of metal. The individual ropes are woven to form the mesh layer with some ropes being positioned in a first or Y direction and the other ropes being positioned in a second or X direction. One or more mesh layers are attached to a metal substrate by rolling, forming or extrusion. The parameters of the rolling, forming or extruding process can be optimized to achieve the proper embedding of the ropes into the metal plate where the ropes are locked into the metal plate with the metal material flowing over the cable outer surfaces without infiltrating between the wires.

Abstract: A method and system for increasing damping capacity in cast metal parts by utilizing dry friction between individual wires of a sheathed rope is disclosed. The rope is embedded into the part during casting. Sheathing the ropes in a thin layer of the same metal as the casting prevents molten metal from infiltrating individual wires during casting, thus allowing inter-wire friction during the part vibration. There are two ways to distribute the ropes within a part during casting. The first way is to distribute the ropes uniformly across an entire part whereby damping capacity of the metal part increases uniformly as well. The second way of distributing the ropes is to spatially distribute them according to a pattern to increase the damping capacity only in the part regions that have the highest vibration amplitudes or stress during system vibration. Both methods of distribution may be combined in a single part.

Abstract: A brake component for a motor vehicle may include a body and at least one cable positioned within the body. The at least one cable may include a plurality of wires positioned relative to one another, each of the plurality of wires having a surface in sliding contact with surfaces of adjacent wires of the plurality of wires. During braking of the motor vehicle, sliding movement of the surfaces of the plurality of wires relative to each other may dampen a resonant frequency of the component.

Abstract: Methods and apparatus to control braking of a vehicle during low deceleration operations are disclosed. A disclosed apparatus includes a controller configured to determine a deceleration of a vehicle, compare the deceleration to a threshold, and modulate, at a predetermined frequency, a brake pressure of the vehicle in response to the deceleration being below the threshold.

Abstract: A brake pad for a motor vehicle is provided. The brake pad includes a body having upper and lower edges and a friction surface extending between the upper and lower edges for engaging a rotor. A notch is located along a section of the upper edge of the brake pad. The notch has an arc length of about ¼ to about ½ of an arc length of the pad and a depth of about ? to about ? of a height of the pad. During engagement with the rotor, the notch is configured to reduce squeal noise caused by tangential modes of the rotor.

Abstract: A brake component may include a body and at least one sheathed cable positioned within the body. The at least one sheathed cable may include a plurality of wires, each of the plurality of wires having a surface in sliding contact with a surface of at least one adjacent wire of the plurality of wires. During braking of the motor vehicle, relative sliding movement between the surfaces of the plurality of wires may dampen a resonant vibration of the component.
