Abstract: 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.

Abstract: An elastomeric bushing for vehicle suspension includes inner and outer metal tubes, an elastomeric material between the tubes, and one or more bundles of woven wires (ropes or cables) in entangled or mesh form wherein at least a portion of the wires contact at least one of the tubes. The bushing has enhanced thermal conductivity via metal-to-metal contact and improved damping capacity to reduce heat buildup inside the material upon cyclic loading and unloading. The metallic wire rope, metallic wire ropes or wire mesh are embedded in the elastomeric material during injection molding where the ends of the wire ropes are attached to the opposing side walls of the inner and outer metal tubes or are spaced apart from the opposing side walls for tunability and to thereby enable a more effective dissipation of the heat generated inside the elastomeric bushing during its usage into the kinematically connected suspension members.

Abstract: A friction damping cast component and method of production are disclosed. The components may be rotary, such as a cast brake rotor, or may be non-rotary, such as a cast suspension part or a cast engine block. Regardless of the type of component, a two-part vibration-damping insert having a thin metal core and a thin metal sheath is provided. The sheath fully encompasses the core in such a way that a dry sliding friction contact develops at their interfaces. The outer surface of the sheath with the metal core inside is rigidly bonded to the cast material that surrounds it during the casting process. The sheath surfaces may have a number of openings that allow a limited infiltration of molten cast iron material just inside the immediate vicinity of the sheath openings for spot rigid bonding between the surrounding cast material and the insert surfaces during casting.
